An Actively-controlled Microwave Reflecting Surface with Binary-pattern Modulation

This article describes an actively-controlled reflecting surface, capable of modulating the microwave energy incident upon it. The surface is a composite structure holding an array of conventional semiconductor diodes excited with a set of pulses in a ...
For specific applications, there is a need for materials or composite structures which can reflect and/or absorb the electromagnetic (EM) energy incident upon them in a desired or controllable fashion. Such reflective EM absorbing/reflecting materials 1-3 are useful in designing smart radar cross-section (smart RCS) surfaces and radio frequency...
