Radar absorption structures made of an active frequency selective surfaces (AFSS) have
enormous potential in the aviation, naval, and other industries. In this research paper, a …

In this paper, a new type of terahertz (THz) metamaterial (MM) modulator has been
presented with bifunctional properties based on vanadium dioxide (VO2). The design …

This article demonstrates a miniaturized flexible multifunctional active frequency selective
surface (MAFSS) with excellent angular stability and polarization insensitivity. The proposed …

This letter proposes a 4-bit multifunctional active frequency selective surface (AFSS) whose
structure is made up of two metallic layers arranged on both sides of a 1.6 mm thick FR-4 …

This letter presents a beam‐steering antenna with an active frequency selective surface
(AFSS). The proposed AFSS‐based antenna consists of a source antenna and an active …

Aiming at angular stability, a frequency-selective surface (FSS) with stable response to TE
and TM polarization at large incidence angles is designed by the gradient-based topology …

In this article, a transmission passband tunable reconfigurable frequency-selective surface
(RFSS) with a wide tuning range is proposed. First, the design guidelines of a wide tuning …

In this letter, a dual-polarized, notched ambient electromagnetic (EM) energy harvester array
based on frequency selective surface (FSS) is presented. The proposed unit structure …

A 1‐bit reconfigurable transmitarray (RTA) is studied in this article for wireless power
transmission (WPT). The type of the RTA is micro‐element embedded active frequency …

In this article, an amplitude-and frequency-tunable coherent perfect absorption (CPA) is
presented using a varactor-embedded frequency selective surface (FSS)-based …
