Design of High-Selective FSR with a Single Layered FSS

A frequency-selective rasorber(FSR) with high frequency-selective property is proposed in this work. Dipoles with two series LC structures are presented on the resistive layer. In addition, a single layer FSS with loop structure is also designed. The equivalent circuits model (ECM) of the FSR is then analyzed. The simulation results demonstrate the high frequency-selectivity of the proposed FSR.
