Power-Dependent Frequency-Selective Surface: Concept, Design, and Experiment

A power-dependent frequency-selective surface (FSS) is presented in this paper. The FSS is able to provide a passband for low-power microwave signals and a stopband for high-power microwave (HPM) signals. Diodes play an important role in achieving this behavior due to their nonlinear property. The operation of such an FSS is studied by analyzing the equivalent circuit model, followed by simulations using circuit element and SPICE model of diodes. The proposed FSS is also demonstrated experimentally. The low-power experiment is carried out using free-space measurements, while the high-power experiment is carried out using a rectangular waveguide. The experiments confirm a rapid reduction of transmitted power at power levels higher than 34 and 18 dBm, respectively, with two different PIN diodes. Such a characteristic offers great potential for use as a protection screen for electronic devices from HPM signals.
