Electronically controllable diode reflector matrix for missiles

摘要

The diode matrix array (Dij) is implanted on an upper layer of silicon carbide (SiC), which is separated from a lower silicon substrate (Si) by an isolating oxide layer (SiO2). The silicon layer is a quarter of a wavelength thick and has a plane metallic reflector backing plate.The diode array reflects high frequency radar signals providing a calibrated reflector.
