Abstract
A dielectric phase hologram integrated with a dual-reflector feed for frequency-diverse submillimeter-wave imaging applications is proposed. The structure is based on Cassegrain optics and consists of a dielectric material with reflective surface coatings acting as primary and secondary reflectors. The hologram integrated into the dielectric aperture surrounding the secondary reflector has a quasi-random surface relief to create complex field patterns in the region of interest at 220-330 GHz.
