Abstract

A method of using memristors as passive electromagnetic switches is demonstrated via full-wave finite-difference time-domain simulations. A memristor is a fundamental circuit element that directly links flux and charge. These circuit elements exhibit a resistive memory effect, which results from a frequency dependent hysteresis. Therefore a memristor can be used as a resistive switch whose resistance varies under low frequency excitation but is unchanged at high frequencies. Utilizing this property, a passive reconfigurable band-pass frequency selective surface that is switched via space waves was designed and simulated.
