Plasma based self-reconfigurable energy selective surface for high-power protection

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper presents an energy-dependent self-reconfigurable frequency selective surface (SRFSS) without an additional biasing network or tuning elements. The proposed FSS can switch the operation frequency with incoming high-power microwaves. The plasma technology is integrated into the FSS design to achieve this reconfigurability. The structure is designed to resonate at ∼6.0 GHz during the plasma OFF (low power) mode. The resonance shifts to ∼3.0 GHz In the presence of a high-power input, plasma ON mode, thus resulting in an independent reconfigurable performance. A prototype is fabricated and tested as proof of the concept, with a unit cell size of 0.15λ × 0.15λ × 0.012λ, which is ultra-thin and compact.
