A frequency selective surface (FSS) absorber with a biasing control system is presented in
this letter. The absorber consists of the top-layer FSS structure, the bottom-layer metal sheet …

An active absorptive frequency selective surface (AFSS) is proposed in this paper, which is
comprised of a switchable bandpass screen and a periodic resistive surface separated by a …

A wide‐band absorber and reflector using PIN diodes based on active frequency selective
surface (AFSS) is presented, which the AFSS is performed as a wide‐band absorber and …

In this letter, we report on the design, fabrication, measurement, and analysis of a tunable
low-frequency and broadband radar absorber applied in the frequency range of 1-12 GHz …

A novel tunable frequency selective surface (FSS) with dual-degrees of freedom (DOF) is
presented, and firstly applied to broadband absorber. Based on a simple prototype unit cell …

A novel design of absorptive frequency selective surface (AFSS) with tunable
absorptive/switchable transmissive property is presented. The AFSS is comprised of a …

In this letter, a switchable frequency selective surface is designed that can operate between
rasorber and absorber having a wide passband characteristics. The structure has an extra …

A new architecture for designing a tuneable wideband absorber using an active frequency
selective surface (AFSS) is presented. The proposed AFSS is composed of 2‐D periodic …

A novel method of designing a frequency selective surface absorber (FSSA) with bandpass
characteristic between two neighboring absorption bands is proposed in this letter. This …

An effective approach to designing a tunable electromagnetic absorber is presented and
experimentally verified; it is based on an idea that an existing frequency selective surface …
