Abstract

Lens are used to manipulate propagation of electromagnetic waves in various applications such as communication, imaging, and sensing. The paper describes the design and characterization of an ultra-wideband reflector lens operating at 300 GHz. The lens is constructed using a single-layer metasurface and the unit cell consists of a single metal ring with two openings. The design achieves an efficiency greater than 90% and a cross-polarization gain of 25 dB over the a bandwidth of over 160 GHz.
