Efficient ultra-wideband nano-antennas are becoming key components for novel photonic applications, such as energy harvesting and optical sensing of particles, fluid refractive index, chemical and biological agents, etc.  Downscaling the well-known configurations of metallic antennas from radio to the optical and infra-red (IR) frequencies offers unique advantages for many of these applications. Furthermore, metallic nano-antennas can be loaded with carbon nano-devices to provide specific functionality. Two types of ultra-wideband highly efficient nano-antenna arrays developed by our group will be described. Also, a novel technique for antenna and load impedance measurements using scattering data will be presented. Various applications of nano-antennas will be discussed.

Biography: Amir Boag received the B.Sc. degree in electrical engineering and the B.A. degree in physics in 1983, both Summa Cum Laude, the M.Sc. degree in electrical engineering in 1985, and the Ph.D. degree in electrical engineering in 1991, all from Technion - Israel Institute of Technology, Haifa, Israel.
