Near-normal incidence quasi-optical reflective Faraday rotator for high power millimeter wave radars

摘要

An optical element having characteristics suitable for use in a Faraday rotator has bonded to each of the adjacent radiation-receiving surfaces thereof with a chamber or water conducting conduit affixed therein includes a water cooled Faraday rotator element having: a base magnet plate substrate; a flowing water filled conduit fixed on the top surface of the base magnet plate substrate; a ferrite waffle iron grid with a binary top surface which reflects radiation and which has a bottom surface; and a fused copper layer fixed between the bottom surface of the ferrite waffle iron grid and the flowing water filled conduit.
