NOMINATOR’S JUSTIFICATION
Martin Bloch designed, developed the processes for, built, and delivered the highest stability and longest life oven controlled crystal oscillators (OCXO), primarily for space and other special applications. He has delivered OCXOs with Allan Deviations of 7 x 10^-14/t. He has also developed state-of-the-art radiation hardened OCXOs, and low acceleration sensitivity OCXOs.
The radiation-hardened oscillators in the Voyager spacecraft were built by Martin Bloch, and under his direction, in 1970. The Voyagers were launched in 1977 and have been operating continuously since then, as of early 2021. During a fly-by of Jupiter the oscillators had been exposed to 100 kilorads of radiation and continued to operate, as designed. These oscillators are the longest life oscillators known. They have operated in space for 43 years and their age since they were built exceeds 50 years.

NOMINATOR’S JUSTIFICATION
I had a chance to work with Sylvain Ballandras, when I was granted “the chair of excellence” for couple of years (2009-2012) in ENSMM, and I worked in close contact with FEMTO-ST, where Sylvain was a scientific leader, director of research. He had a “school” of dozens of Ph.D. students. We also worked together in two EU Projects.
Most impressive application of micro-acoustic resonators is in SAW filters for mobile communications. Resonators also play the main role in passive sensors, especially for severe environment, where Si-based device fail. Sylvain Ballandras is a key contributor to all these areas:
- Simulation tools. For the SAW resonators used in filters for mobile phones the main issue is to get high Q-factor and accurately predictable other parameters. FEM/BEM software for simulation multi-layered devices
was first developed by Sylvain and his co-workers. S. Ballandras was the leader in development of first 3D software packages for the resonator modeling, as projects for SAW industry. He developed stable scattering matrix methods for SAW in multilayered structures. - Phononic crystals. His pioneering works created area of “phononic crystals”, and now well-known specialists (Prof. V. Laude, Prof. A. Kelif, …) were his students/coworkers.
- High temperature sensors. This is a topic which attracted S. Ballandras during many years. He studied resonators based on LGS (langasite) - the high temperature piezoelectric, AlN on sapphire, high temperature packaging.
- Thin piezoelectric layers. His paper on film bulk acoustic resonators with X-cut LiNbO3 layer transfer – is a pioneering work, which was ahead of its time and only now are becoming practically important – for extremely wide-band filters for 5G phones.
So, S. Ballandras is an outstanding scientist which made basic contributions for development of piezoelectric resonators. Now he tries to realize his ideas himself, in frames of his small company, Freq¦n¦sys, belonging to Soitec.

NOMINATOR’S JUSTIFICATION
Sunil excels in inventing transducers, fabrication techniques and studying inter-domain coupling between MEMS, photonics and magnetics, with the goal of demonstrating superior RF components and Inertial Sensors. He pioneered dielectric‐transduced MEMS resonators (ie. no air gap, piezo‐electric coupling) and invented, together with his graduate student Dana Weinstein, the Resonant Body Transistor. In this design, the resonators are part of the transistor structure, next to the gate, and the coupling between the resonator and the transistor can be at a high impedance (gm‐level coupling). As Dana continued the research at MIT, Sunil moved his group into a new area, which is the interaction of MEMS resonators and optics, and achieved recently some phenomenal results in optical oscillators (the first “portable” optical‐acoustic oscillator demonstrated to DARPA at the David Howe lab at NIST), optical MEMS modulators, optical‐MEMS photon detectors and opto-mechanical gyroscopes. All of these are “high performance” systems and he established himself as a leader in this field after a short 3-4 years. Recently Sunil has started research in investigating coupling between MEMS resonators and magnetic systems. He has successfully coupled a high-Q HBAR resonator with Spin Torque magnetic oscillators to demonstrate a VCO with exceptional phase noise and tuning range. And most recently, along with his colleague Greg Fuchs, he was the first to demonstrate Rabi oscillations in color center “atom-like” systems using ultrasonic actuation of diamond resonators.
This what I admire about Sunil: he is versatile, is always thinking of new applications and is not afraid to dive into new areas, learn from them, and couple them with MEMS technology to advance fundamental understanding and define new opportunities for these hybrid systems.

In Bucharest, Cipriana Tomescu constructed in collaboration with colleagues 9 Hydrogen masers that were used by the Bucharest Observatory, the Institute of Physics and the Physics Faculty in their research programs.
During 1992-2006, she was invited as researcher in several institutions : Neuchatel Observatory, Switzerland, National Bureau of Metrology, France, and Communication Research Laboratory, Japan. In those laboratories, she spent periods of several months in each of those, initiating and working in projects on atom cooling for use in atomic fountains and in developing atomic clocks based on the concept of the fountain.
While at SYRTE in Paris, she was instrumental in the construction of a Cs-Rb fountain that reached an accuracy of 10-16, a realization that has made possible an early evaluation of the drift of fundamental constants to less than 10-16 in a year or so.
In 2008, she was invited at the University of Liège, Belgium, within a University -Gillam FEI cooperation (Plan Marshall SKYWYN) as chief scientist responsible for the establishment of a research program on atomic frequency standards. Her main task consisted in the construction of a first hydrogen maser. She accomplished that task with great success.
She is the author or co-author of 92 publications in either scientific journals or conference proceedings. Under invitation from Taylor and Francis, she co-authored a book titled The Quantum Physics of Atomic Frequency Standards, Recent Developments (Vanier-Tomescu), 466-pages, 2016, describing recent developments in the field of atomic clocks. She also co-authored Universe Dynamics, the Least action Principle and Lagrange’s Equations, (Vanier- Tomescu) 183 pages, 2019. Both books have received a very positive appraisal.

NOMINATOR’S JUSTIFICATION
While Dr. Ekkehard Peik currently heads the Time and Frequency Department at Physikalisch-Technische Bundesanstalt (PTB) in Germany, his leadership in optical time and frequency research and metrology extends to a much further, global reach. In particular, he has made longstanding and deeply impactful contributions to the development of trapped ion optical clocks. Beginning as a young graduate student, he helped observe the first Coulomb crystals of laser cooled ions and developed a version of the Paul trap widely-used since. He later made the first optical frequency measurements of a trapped ion using an optical frequency comb. At PTB, he led the development of the trapped ion optical clock based on ytterbium, exploiting both the narrowband quadrupole and octupole transitions. This clock reached the lowest systematic uncertainty of any optical clock at the time, an astonishing 3x10-18 fractional frequency, and further demonstrated frequency stability below this level. Together with his research team, he has used this clock as an ultra-sensitive probe in the search for beyond-Standard-Model physics such as the time variation of fundamental constants and the search for dark matter, as well as tests of relativity such as violations of Lorentz invariance. In tandem with his PTB colleague Christian Tamm, he developed the concept of a nuclear clock using 229-thorium. Research supporting this idea is now carried out in labs around the world, and has the potential to further revolutionize optical time and frequency metrology. He has contributed more than 100 technical publication to the scientific literature, many that are highly impactful. He has also supervised more than twenty graduate students or postdoctoral researchers in this field. Finally, he has provided extensive leadership to the international time and frequency community through his service within EFTF, IFCS, UFFC, and CCTF.

NOMINATOR’S JUSTIFICATION
Over the last two decades, Dr. Udem has made major contributions to precision spectroscopy of atomic hydrogen and the precision measurement of optical frequencies via optical frequency combs. Dr. Udem’s first major contributions
to this important field were made in the late 1990s, when, in collaboration with Prof. Ted Hansch, he pioneered the optical frequency divider, a method for precisely bisecting optical frequencies. The success of the optical frequency divider enabled phase-coherent measurements of the hydrogen 1S-2S transition frequency with unprecedented precision with respect to a methane-stabilized HeNe laser, and ultimately to the SI second. This measurement led to the most accurate determination at the time of both the Rydberg constant and the Lamb shift of the hydrogen ground state.
This pioneering work on optical frequency dividers laid the foundation for the development by several groups of optical frequency combs and optical clocks based on femtosecond lasers. This now expansive field of research was awarded the Nobel Prize in Physics in 2005. Dr. Udem advanced comb technology significantly, and carried out a number of spectroscopic measurements with frequency combs including the 1S-2S transition frequency in hydrogen, the frequency of the Cs D1 line, the frequencies of transitions in molecular iodine and the “clock” transition frequencies of Hg+, In+ and neutral Ca. The optical frequency comb has been a key enabling technology for the current generation of optical atomic clocks, and Dr. Udem played a key role in their development including major contributions to the demonstration of the first optical clock based on Hg+.
More recently, Dr. Udem has led efforts to use stable frequency comb technology in the search for planets orbiting distant stars and to help clarify the proton radius puzzle, a longstanding problem in fundamental physics.

NOMINATOR’S JUSTIFICATION
The IEEE Standard 1139-2008 states that the oscillator phase power spectral density has five independent noise processes with slopes f0, f-1, f-2, f-3, f-4 in the Fourier frequency f domain. To predict clock errors accurately, a state estimator must be tuned to all of them or at least to f0, f-1, and f-2. The Kalman filter (KF) fits with white Gaussian noise f0 and cannot properly process time signals. Another estimator, which ignores any information about zero mean noise, was designed for clocks by Dr. Shmaliy in [1,2] and called the unbiased finite impulse response (UFIR) filter. The p-shift UFIR filter was then derived in [3] to be a filter (p=0), smoother (p<0), and predictor (p>0), extensively investigated in [4-11], generalized in a book [12], referred to by many authors as a robust alternative to KF, and used in different areas (certificates). The UFIR filter produces smaller errors than the KF in applications to clocks and also fits better with the requirements of the IEEE Standard 1588TM-2002 for precision clock synchronization [6]. Nowadays, the state estimation theory offers only two basic recursive schemes [5]: optimal by Kalman and robust unbiased by Shmaliy. Therefore, Dr. Shmaliy was invited 39 times to give talks to different symposia and Universities. Most recently, the UFIR filter was developed to fit with the f-2 clock noise [7] and f-2 measurement noise [10]. Of a special significance is that the unique FIR functions derived by Dr. Shmaliy [2] and used for clock interpolation [8] and extrapolation [9] establish a new class of discrete orthogonal polynomials (DOP) [11] referred to as Discrete Shmaliy Moments (DSM). The DSM were shown by several authors to be more suitable for signal approximation than the classical DOP and Chebyshev polynomials. The optimal and unbiased FIR state estimation theory developed by Prof. Shmaliy has been used in his graduate and postgraduate courses [13,14] on optimal clock synchronization and optimal and robust state estimation as well as in research and MS and PhD projects of many his students. An invited tutorial on optimal FIR filtering of clock models has been given by Dr. Shmaliy to the EFTF/IFCS in 2009.

NOMINATOR’S JUSTIFICATION
Dr. M. Solal has made a significant contribution to resonator filter design and creating new resonator structures, development of methods of their simulation, optimization, and design. His key contributions are:
- Development of first ever FEM/BEM software package — together with P. Ventura and others. That was a first in this world “exact” software, which needed only material parameters for simulation and design of devices.
- Invention, development, and production of the “resonant SPUDT” — very low loss SAW filters which included unidirectional transducers with resonating structure inside it. Thales filters based on this approach were the best in the industry.
- First SAW resonators using a thin piezoelectric layer (LN at that time) bonded on Si. This is a technology which was the precursor of current IHP technology from Murata and XBARs.
- SAW Resonators with the “piston mode” operation — this invention of Marc present today in every mobile phone!
- His upcoming innovations presented recently (developed with Shogo Inoue) — on anew LT/quartz substrate providing a near-zero ATCF with drastically reduced transverse mode level — work of year 2020.
Marc always worked in leading SAW companies (Thales, and then Qorva) and his publications are not so numerous as that of university researches/Professors, but they contain real knowledge. He is the author of many inventions used in Qorvo filters. | had a great chance to work with Marc Solal in Thales for a few years. | have co-authored a few papers with Marc. Marc is one of the most creative workers in the SAW industry. His ideas and his example influenced many people. Younger colleagues, who worked with him in Thales are now leaders in the main SAW companies.
Dr. Marc Solal is an outstanding contributor to the SAW and micro-acoustic device area, the leader in our scientific community who created revolutionary new resonator structures.
