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 ...

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.

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 ...

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.

Traditional Frequency Selective Surface versus Substrate Integrated Waveguide Frequency Selective Surface [PDF]
Universal Journal of Communications and Network, 2014 This paper is devoted to analysis design and fabrication of both traditional and substrate integrated waveguide (SIW) frequency selective surfaces (FSS) of square elements and square lattice. The transmission loss is studied for different angle of incidence; normal, thirty, forty five and sixty degrees.
