Singly and Dual Polarized Convoluted Frequency Selective Structures [PDF]

, 2010
Convoluting the elements of frequency selective surfaces produces resonating structures with very small unit cell dimensions. This feature is attractive when the FSS is to be used at low frequencies, mounted on a curved surface, or when placed in the ...

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.

Broadband Frequency Selective Rasorber Based on Spoof Surface Plasmon Polaritons

Micromachines, 2022
A broadband frequency selective rasorber (FSR) based on spoofsurface plasmon polaritons (SSPP) is proposed. The FSR is composed of a multi-layer structure comprising frequency selective surface (FSS)-polyresin (PR)-indium tin oxide (ITO)-PR-FSS and ...

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.

Angular independent frequency selective surfaces for interference control in indoor wireless environments [PDF]

, 2012
A study of electromagnetic wave propagation in buildings using a finite-difference time-domain algorithm has demonstrated that waves are incident on walls over a wide range of angles. If wall mounted frequency selective shielding is desired, it is argued
