Electromagnetic (EM) waves are widely used in modern life, as they serve many of mankind’s basic needs such as communication (mobile phones for instance), navigation (GPS), sensing (radars), medical diagnostics and treatments, material processing, food preparation and security. Electromagnetics provides therefore an essential scientific foundation for large families of technologies which are critical for the well being of almost any society and individual in the 21st century. In view of this, our theoretical and experimental research activities span from fundamental studies to advanced developments of novel devices and components. Our studies include, for instance, analyses of EM-wave propagation, scattering and diffraction in complex structures, ultra-wideband and short-pulse electromagnetics, and target identification and inverse scattering. In the section of antenna theory and techniques, we develop modeling techniques for complex antenna systems, design and develop advanced antennas, and investigate novel concepts of nano-antennas in the wider scope of nano-electromagnetism. In the millimeter-wave range, we develop high-power sources, including free-electron lasers and masers, and study EM energy transmission in the atmosphere. In another branch, we investigate EM-wave interactions with natural and artificial materials, photonic crystals, and plasmas. The latter involve also syntheses of nano particles, such as carbon nano-tubes and silicon micro-spheres. Our developments of advanced integrated circuits include novel schemes of RFIC's and mm-wave CMOS circuits, also for integrated communication and sensing circuits. These and other EM-related studies conducted in our department create a leading knowledge center which contributes to the scientific community, supports the industry, and advances our engineering students on all levels.
