The intent of this paper is to provide an overview of basic concepts, types, techniques, and
experimental studies of the current state-of-the-art Frequency Selective Surfaces (FSSs) …

Three-dimensional (3-D) frequency-selective structures are a recent development that
exhibit superior filtering responses compared to conventional two-dimensional (2-D) …

In the present scenario, there are prime challenges that need to be addressed in modern
wireless communication systems. These challenges consist of implementation of techniques …

Frequency-selective surfaces (FSSs) have many applications in spatial filtering of
electromagnetic waves and are commonly used in antennas, polarizers, radomes, and …

This communication presents a 3-D frequency-selective rasorber (FSR) that has a passband
with a low insertion loss and two absorption bands at both sides of the passband. A lossless …

A multilayer structure and magnetic ferrite material are employed to expand the absorption
bandwidth of 3-D frequency-selective rasorber (FSR). Resonant-like ferrite is used to realize …

A new design method based on a folded substrate is proposed in this paper to reduce the
thickness of 3-D bandpass frequency-selective structure (FSS). A 67% and 79% thickness …

A new class of three-dimensional (3-D) bandpass frequency-selective structures (FSSs) with
multiple transmission zeros is presented to realize wide out-of-band rejection. The proposed …

In this paper, a miniaturized ultra-wide stop-band frequency selective surface (FSS) with
angular stability and polarization insensitivity is presented. The FSS is composed of four …

In this article, an absorptive energy-selective structure (ESS) based on a 3-D structure
mounted with pin limiter diodes is proposed for achieving high-power electromagnetic …
