President Obama Honors Outstanding Early-Career Scientists

July 9, 2009

President Obama today named 100 beginning researchers as recipients of the Presidential Early Career Awards for Scientists and Engineers, the highest honor bestowed by the United States government on young professionals in the early stages of their independent research careers.  The recipient scientists and engineers will receive their awards in the Fall at a White House ceremony.
The Presidential Early Career Awards embody the high priority the Administration places on producing outstanding scientists and engineers to advance the nation’s goals and contribute to all sectors of the economy.  Nine Federal departments and agencies join together annually to nominate the most meritorious young scientists and engineers—researchers whose early accomplishments show the greatest promise for strengthening America’s leadership in science and technology and contributing to the awarding agencies' missions.

"These extraordinarily gifted young scientists and engineers represent the best in our country," President Obama said.  "With their talent, creativity, and dedication, I am confident that they will lead their fields in new breakthroughs and discoveries and help us use science and technology to lift up our nation and our world."
The awards, established by President Clinton in February 1996, are coordinated by the Office of Science and Technology Policy within the Executive Office of the President. Awardees are selected on the basis of two criteria: Pursuit of innovative research at the frontiers of science and technology and a commitment to community service as demonstrated through scientific leadership, public education, or community outreach. Winning scientists and engineers receive up to a five-year research grant to further their study in support of critical government missions.

Among the 2010 recipients of the Presidential Early Career Award for Scientists and Engineers is
Anthony Grbic, University of Michigan.

Professor Anthony Grbic

Prof. Anthony (Tony) Grbic, assistant professor in the Radiation Laboratory, was awarded the highly prestigious Presidential Early Career Award for Scientists and Engineers (PECASE), announced July 9, 2009 by The White House. The PECASE is the highest honor bestowed by the U.S. government on outstanding scientists and engineers beginning their independent careers. Tony joined U-M in 2006 after receiving his M.A.Sc., M.A.Sc., and Ph.D. degrees in electrical engineering from the University of Toronto.

Prof. Grbic pursues both experimental and theoretical research in electromagnetics and microwave circuits. His research program involves both basic science (e.g. multidisciplinary work on metamaterials and near-field plates) as well as advanced technology development (e.g. antenna research and design, wireless component development).

He is a pioneer in the field of electromagnetic metamaterials, publishing highly influential papers even while working on his dissertation at the University of Toronto. His more recent work in this area is focused on the development of a special class of volumetric metamaterials which can overcome the bandwidth and loss limitations of current metamaterial designs. The superior performance of these metamaterials will allow them to be integrated into practical microwave focusing and antenna systems.

He is now breaking ground in a new area that is of great interest among researchers, near-field superlenses, by pursuing an entirely new approach to manipulating and focusing the electromagnetic near field, which relies on modulated grating-like surfaces referred to as near-field plates (NFPs). NFP's hold promise for a number of areas including high resolution probing devices, quasi-optical and optical components, devices for wireless non-radiative power transfer, as well as antennas and nano-antennas. In this work, he is actively collaborating with physics professor Roberto Merlin.

The article, "Near-Field Plates: Subdiffraction focusing with patterned surfaces,Ć by Anthony Grbic, graduate student Lei Jiang, and physics professor Roberto Merlin, appeared in Science, vol. 320, no. 5874, pp. 511-513, April 25, 2008. His research activities have also been been cited in Scientific American, Nature, Physics World, Physics Today, New Scientist, Discover Magazine and EE Times.

Prof. Grbic has received an AFOSR Young Investigator Award and an NSF Faculty Early Career Development Award. He is very active in professional societies, and is already a frequently invited speaker at professional conferences and symposiums. He teaches courses in introductory Electromagnetics, senior level Radiowave Propagation and Link Design, and graduate courses in Electromagnetic Metamaterials.

The PECASE Awards are intended to recognize some of the finest scientists and engineers who, while early in their research careers, show exceptional potential for leadership at the frontiers of scientific knowledge during the twenty-first century. The Awards foster innovative and far-reaching developments in science and technology, increase awareness of careers in science and engineering, give recognition to the scientific missions of participating agencies, enhance connections between fundamental research and national goals, and highlight the importance of science and technology for the nation's future.

Several agencies participate in the PECASE awards. Prof. Grbic received his award from the Department of Defense, U.S. Air Force Office of Scientific Research.


At the University of Zagreb, Croatia (Faculty of Electrical Engineering and Computing) in 2014:
Professors Juraj Bartolić, Zvonimir Šipuš, Anthony Grbac (project co-leader), Silvijo Hrabar (project leader),
Radovan Zentner and Davor Bonefačić.

Professor Anthony Grbic visited his Croatian colleagues at the Univeristy of Zagreb

As a part of the project prof. Anthony Grbic visited the electromagnetic group at the University of Zagreb, Faculty of Electrical Engineering and Computing (14th -22nd October 2014). During the visit, the partners defined forthcoming activities in modeling of metastructures and their experimental characterization. Prof. Grbic also gave an IEEE talk with the title “Metasurfaces for Manipulating Electromagnetic Waves.” The summary of the talk is given below.

Metamaterials have provided unprecedented control over electromagnetic fields. However, their notable thickness has often led to fabrication challenges and added loss. This has motivated the development of metasurfaces:  the two dimensional analog of metamaterials. Metasurfaces are surfaces textured at a subwavelength scale to achieve tailored electromagnetic properties. They fall into two broad categories. The first class of metasurfaces manipulate electromagnetic wavefronts incident from free space.  This type of metasurface tailors the wave transmitted through it, or reflected from it. The second class of metasurfaces guide or radiate waves. The metasurface acts as either a waveguiding structure or supports leaky waves that radiate directive far-field patterns. This talk will describe the development of both types of metasurfaces.

Reflectionless metasurfaces (Huygens’ metamaterial surfaces) that can steer, focus and manipulate the polarization of transmitted electromagnetic waves will be described. These metasurfaces possess both electric and magnetic responses, which allow them to be impedance-matched to the surrounding space. Different metasurfaces that allow polarization control, beam deflection and focusing will be presented.  Bianisotropic metasurfaces with enhanced field tailoring properties will also be touched upon.

A systematic approach to designing these new metasurfaces will be introduced, and a few experimental devices reported to demonstrate the capabilities of this technology. Next, a new approach to designing 2D inhomogeneous, anisotropic media will be described. The design methodology allows the design of 2D media that support desired spatial distributions of the wave vector and Poynting vector direction. Its utility in the design of metasurfaces will be demonstrated through different design examples.

The proposed method allows arbitrary control of electromagnetic fields within a 2D medium. Such spatial control of phase and power flow allows one to mold the phase and amplitude of an aperture field. Preliminary results of a beamformer designed using the proposed methodology will be shown. Finally, the synthesis of radiation patterns using conductor-backed metasurfaces (impedance surfaces) will be explored.  A synthesis procedure enabling the design of low-profile, leaky-wave antennas with prescribed far-field patterns will be demonstrated.


We express our sincere gratitude to Zvonimir Šipuš, Professor at the University of Zagreb,
for his kind information about Professor Anthony Grbac.

It is little known that William Feller (1906-1970), born in Zagreb, Croatia, professor of Mathematics at the Princeton Univeristy,
was awarded by the National Medal of Science in 1970 in the filed of Mathematical Sciences.
