Abstract

Single-crystal silicon is bonded to a metal-coated substrate and etched in order to form an array of microcylinder passive terahertz dielectric resonator antennas (DRAs). The DRAs exhibit a magnetic response, and hence the array behaves as an efficient artificial magnetic conductor (AMC), with potential for terahertz antenna and sensing applications.

Keywords: artificial magnetic conductors; dielectric resonator antennas; dielectrics; reactive ion etching; terahertz devices.
