A METHOD TO ADJUST ENHANCED X-BAND MICROWAVE TRANSMISSION AND BEAMING USING ASYMMETRIC GRATINGS

摘要

We present a method to adjust enhanced X-band microwave transmission and beaming through controlling the distance between grooves on the front and back surface of asymmetric gratings. Extraordinary transmission and beaming effect was influenced at X-band microwave frequencies (8-12 GHz). It demonstrates a new way to achieve directional selectivity in microwave frequencies.
