Leung Tsang’s pioneering statistical electromagnetic and microwave remote sensing theories have profoundly impacted the fundamental understanding of how microwaves interact with complex geophysical environments. Airborne and satellite remote sensing technologies are central to research in environmental issues such as global climate change and monitoring of Earth’s water and carbon cycles. Dr. Tsang’s models provide pivotal understanding for wave propagation in dense media, random media, rough surfaces, backscattering enhancement, clustered particles, multiple scattering, and four Stokes parameters in thermal emission. His theories have set the standards for active and passive microwave remote sensing of terrestrial and polar snow, soil moisture, vegetation, forest, ice, and ocean wind and foam.

One of the top 50 leaders in science and technology according to Scientific American magazine, Nader Engheta’s pioneering work has profoundly impacted electromagnetics and spurred the growth of many subdisciplines such as metamaterials, nanoscale optics, bio-inspired imaging, and fractional electromagnetics. Dr. Engheta paved the way to the characterization of metamaterials with groundbreaking electromagnetics concepts during the 1990s. He formalized wave propagation in chiral materials and developed the omega media concept, both fundamental to the development and operation of most metamaterials. One of his trailblazing contributions was the development of the new area of optical metatronics, i.e., metamaterial-based optical nanocircuitry. These circuits operate via light at the nanoscale using lumped-element metamaterial nanostructures as inductors and capacitors. Dr. Engheta also contributed to producing metamaterial lenses that can go beyond the diffraction limit inherent to conventional optical lenses. He proposed a far-field super lens made out of shells of alternating dielectric and plasmonic materials capable of projecting a super-resolution image to the far field.
An IEEE Fellow, Guggenheim Fellow, and a Fellow of four other scientific organizations (APS, OSA, AAAS, and SPIE), Dr. Engheta is currently the H. Nedwill Ramsey Professor of Electrical and Systems Engineering and a Professor of Bioengineering at the University of Pennsylvania, Philadelphia.
Yahya Rahmat-Samii’s pioneering contributions to developing sophisticated antennas can be seen in billions of cell phones, millions of satellite dish antennas, and space technology for remote sensing and planetary missions. Dr. Rahmat-Samii developed innovative methods for analyzing and designing modern reflector antennas important to NASA’s space research. He was one of the inventors of the plane-polar near-field technique used to measure the performance of the Galileo spacecraft antenna. He was a principal developer of the microwave holographic diagnostic technique used to improve the performance of NASA’s Deep Space Network. His important research on how electromagnetic waves interact with human tissue led to the development of internal antennas for cellular phones that are a key component of modern handsets. His work on genetic and particle swarm algorithms for electromagnetic optimization has been successfully used by universities and companies designing antennas for wireless communications.
An IEEE Fellow, Dr. Rahmat-Samii is the Northrop Grumman Chair Distinguished Professor at the University of California, Los Angeles.
An applied mathematician and researcher of over 50 years, Thomas B.A. Senior has performed pioneering work in radar cross section (RCS) control, a measurement of how detectable on object is by radar. He created many of the analytical tools needed to predict how RCS reduction can be accomplished using shaping and radar-absorbing materials. Important to stealth aircraft development, which requires a low RCS measure, his findings have played a leading role in current RCS technology.
Dr. Senior demonstrated how radar-absorbing coatings, smooth surfaces and body angles designed to scatter radar waves away from a receiver enable a low RCS. He was the first to recognize how large wind turbines can cause interference to electromagnetic systems, such as television, and developed procedures that are now part of all environmental assessments of these machines.
An IEEE Life Fellow, Dr. Senior is currently an Emeritus Professor with the University of Michigan’s Department of Electrical Engineering and Computer Science.
Kenneth K. Mei is one of the most innovative researchers in computational electromagnetics. His work over four decades has led to solutions in electromagnetic problems that would have otherwise been too large even for computers to handle.
Dr. Mei’s Ph.D. work on formulating Maxwell’s equations into integral equations, now known as the “method of moments,” is credited as the beginning of the era of computational electromagnetics and perhaps one of the most important and widely used numerical analysis techniques for analyzing scattering, antenna and microstrip circuit problems. He was able to show that there are circuits whose solutions should be identical to the solutions of Maxwell’s equations of the same problem, which better demonstrates correct behavior at both low and high frequencies. This will play an important role in keeping devices small even as the integrated circuit technology itself reaches its size reduction limits.
An IEEE Life Fellow, Mei is an honorary professor at the City University of Hong Kong, Kowloon, an adjunct professor at Shanghai University of China and Professor Emeritus at the UC, Berkeley.

These later became parts of radar and communications systems. Dr. Wiesbeck’s research on remote sensing, specializing in high-resolution radars with digital beam-forming, gave him a leading position in the design of mono- and dual-polarization, wideband to ultra-wideband antennas.

He is most famous for developing the Singularity Expansion Method (SEM), which compactly and parametrically represents the late-time electromagnetic scattering and gives an aspect-independent radar signature for target identification. He also introduced the concepts of natural frequencies, natural modes, and coupling coefficients that could be computed from an integral equation to concisely represent experimental data.
Dr. Baum is an authority on electromagnetic pulse simulation (EMP) and has designed simulators for testing various electromagnetic systems used by the U.S. Air Force as well as allied and friendly countries. His excellent design of a special class of antennas, used for accurate transient/broadband measurements of electromagnetic fields and related parameters, are now in standard use by the EMP community in both the U.S. and Western Europe.
