Radiation-Pattern-Reconfigurable Graphene Leaky-Wave Antenna at Terahertz Band Based on Dielectric Grating Structure

Based on the dielectric grating structure, the concept and design method of a novel reconfigurable graphene leaky-wave antenna (LWA) working at terahertz band is presented. The leaky-wave mode is excited by using the dielectric grating, while the applied bias voltage is varied to control the surface...
