Abstract

We overview the research results on electromagnetic optimization and experimental realization of low- and high-aspect plasmonic structures designed for simple and sophisticated focusing at the frequencies of 0.35 and 0.65 THz. The structures are considered both in the reflect and transmit-array configurations whose surface phase distribution is synthesized with a computer holography technique. The overall diffraction efficiency reaching 80% is experimentally demonstrated. The methods of structure fabrication using UV and deep X-ray lithography are discussed.
