This article analyzes a review of recent developments in the field of frequency selective
surface (FSS)-based advanced electromagnetic (EM) structures. FSSs have been the …

Radar-absorbing materials are used in stealth technologies for concealment of an object
from radar detection. Resistive and/or magnetic composite materials are used to reduce the …

A varactor-tunable second-order bandpass frequency-selective surface (FSS) for microwave
frequencies is presented in this article. The FSS is composed of three stacked metallic …

Radar-absorbing materials are used in stealth technologies for concealment of an object
from radar detection. Resistive and/or magnetic composite materials are used to reduce the …

We present a low-profile miniaturized-element frequency-selective surface (MEFSS) with
narrowband, second-order bandpass response. The miniaturized-element unit cell …

Smart tunable electromagnetic materials can regulate and control their electromagnetic
parameters by applying an external field, thus realizing the goal of smartly and actively …

A three-layer frequency selective surface (FSS) tunable absorbing filter is presented.
Tunability is achieved through the use, in every FSS layer, of commercially available, low …

A lightweight, heterogeneous, three-dimensional network-structured composite has been
meticulously developed with the specific goal of optimizing impedance matching and …

The development and performance evaluation of a thin, broadband, and tunable radar wave
absorber with reduced complexity is a strenuous task. This Letter reports the design …

Although conventional (ie, passive) radar absorbers are widely used for modifying the radar
cross-section (RCS) of current military platforms, such absorbers may not have adequate …
