Efficient terahertz reflectarray based on dielectric resonator antennas

We employ single-crystal silicon dielectric resonator antennas for a beam-shaping terahertz reflectarray. The reflected wavefront is shaped by local phase discontinuities introduced by the resonators. Unit-cell simulations show potential for highefficiency operation, and the performance of the refle...

Summary:We employ single-crystal silicon dielectric resonator antennas for a beam-shaping terahertz reflectarray. The reflected wavefront is shaped by local phase discontinuities introduced by the resonators. Unit-cell simulations show potential for highefficiency operation, and the performance of the reflectarray is experimentally verified.
