A Dual-polarized FSS on a Single Substrate using Highly-coupled Interlayer Inductance

Abstract

This paper describes a reconfigurable FSS loaded with varactors for manipulating the vertical and horizontal impedance with incrementally configured DC voltage bias. Highly coupled unit cell topology featuring near-zero separation (λ 0 /250 at 2.4 GHz) leads to rapid impedance tranThis paper describes a reconfigurable FSS loaded with varactors for manipulating the vertical and horizontal impedance with incrementally configured DC voltage bias. Highly coupled unit cell topology featuring near-zero separation (λ 0 /250 at 2.4 GHz) leads to rapid impedance transition with an extremely low insertion loss in the electrically transparent state and high reflections in the electrically opaque state. Equivalent circuit analysis is introduced and experimental measurement confirms this approach.sition with an extremely low insertion loss in the electrically transparent state and high reflections in the electrically opaque state.
