Title

Active Frequency Selective Surface for Strain Sensing

Abstract

This paper presents an active frequency selective surface based sensor for strain measurement. The sensor features two FSS designs; a passive loaded cross dipole on one side of the substrate, and an active (including PIN diodes) rectangular loop on the other side of the substrate. As such, the sensor has two reflection resonances at 1.78 and 2.38 GHz for the OFF state of the PIN diodes, and one reflection resonance at 1.8 GHz for the FWD state. Strain sensing can be accomplished by monitoring changes in the second resonance in the OFF state, and energy harvesting can take place at the first resonant (that is present for both states of the diode).
