A Tri-band Second-order Frequency Selective Surface Designing and Analysis [PDF]
E3S Web of Conferences, 2021 In this paper, inspired from the technique of patch–aperture–patch, a novel tri-band frequency selective surface with second-order band-pass response in each operation band is presented.

Frequency Selective Buildings Through Frequency Selective Surfaces [PDF]
IEEE Transactions on Antennas and Propagation, 2011 This paper proposes the deployment of frequency selective surfaces (FSS) in indoor wireless environments and investigates their effect on radio wave propagation. FSS can be deployed to selectively confine radio propagation in indoor areas, by artificially increasing the radio transmission loss naturally caused by building walls. FSS can also be used to

A polarization‐insensitive time‐modulated frequency‐selective surface for broad frequency range
IET Microwaves, Antennas & Propagation, 2022 Usually, Radar signature of an object is reduced using microwave absorber surface. Recently, another approach based on time‐modulated frequency‐selective surfaces has been developed to deceive Radar detection by selectively generating harmonics/sidebands.

Inkjet printing of frequency selective surfaces [PDF]
Electronics Letters, 2009 As a step towards low-cost manufacture of conducting arrays for frequency selective surfaces, an inkjet procedure is under development. The plane wave transmission response of a printed array compares well with its conventionally etched counterpart and the predictions of modelling software.

An Ultraminiaturized Dual-Stopband Frequency Selective Surface for Ultra High Frequency
IEEE Access, 2020 In this paper, an ultraminiaturized dual-stopband frequency selective surface (FSS) for ultra high frequency (UHF) is investigated. The proposed FSS uses one dielectric layer with two different metal layers printed on its surfaces and the metal layers ...

Active Frequency Selective Surface With Wide Reconfigurable Passband
IEEE Access, 2019 This paper presents an active frequency selective surface (AFSS) with a wide reconfigurable passband. The tuning mechanism was investigated with an equivalent circuit which consists of a parallel L-C resonant circuit and a series L-C resonant circuit.

SWITCHABLE SPLIT-RING FREQUENCY SELECTIVE SURFACES [PDF]
Progress In Electromagnetics Research B, 2008 Tunable frequency selective surfaces (FSSs) based on split ring resonators (SRRs) are presented. Tuning performance is achieved by means of several on/off switches placed between the rings of each SRR element. The band-stop FSS response is dynamically tuned to different frequency bands at different switching states.

Dual-Band Frequency Selective Surface With Compact Dimension and Low Frequency Ratio
IEEE Access, 2020 In this paper, frequency selective surface (FSS) with low profile, miniaturized structure and closely located dual-band is proposed based on the fractal technology. The FSS is designed by etching the conductive pattern on a single layer substrate.
