Wide-Angle Domain Compatible Flexible Multispectral Stealth Metasurface for Visible Light, Laser, and Microwave. [PDF]
NanophotonicsA flexible, wide‐angle‐compatible multispectral stealth metasurface is proposed. It achieves visible camouflage and stable cooperative stealth of 10.6 μm laser and X‐band microwave across the 0°–60° incident range via layered wavelength decoupling. ABSTRACT As electromagnetic detection systems evolve toward multispectral integration and 0°–60° wide ...

NEW TECHNIQUE FOR SIMULATION OF FREQUENCY SELECTIVE SURFACES ( FSS ) [PDF]
International Conference on Aerospace Sciences and Aviation Technology, 2011 Two dimensional periodic arrays of patch elements can be used as frequency selective surfaces (FSS) owing to the frequency filtering properties of these structures. Arrays of square loops are of interest as frequency selective surfaces for dichroic reflector antennas.

Compact Frequency Selective Surface (FSS) for X-Band Shielding
International Journal of Innovations in Science and Technology, 2022 With the increase in the usage of electromagnetic devices, electromagnetic interference increased many folds. Frequency Selective Surface (FSS) provide effective shielding from unwanted frequency ranges. A thin, conformal band-stop FSS is presented in this research that provides effective electromagnetic shielding properties in X-band.

Band-Stop Frequency-Selective Surface (FSS) with Elliptic Response Designed by the Extracted Pole Technique. [PDF]
Sensors (Basel)This paper describes and validates an advanced synthesis design process of Frequency-Selective Surfaces (FSSs) with elliptic band-stop responses. A systematic procedure based on the Generalized Chebyshev Function and the extracted pole technique enables control of the position of the transmission zeros and the attenuation level to obtain an equiripple ...

A Miniaturized Frequency Selective Surface Based on Square Loop Aperture Element
International Journal of Antennas and Propagation, 2014 We propose a miniaturized band-pass frequency selective surface (FSS) with periodic unit cell structure. The proposed FSS is realized by symmetrically bending the edges of the square loop aperture element, by which our proposed FSS increases the resonant

Design of a Hemispherical Reconfigurable Frequency Selective Surface Using Water Channels
IEEE Access, 2018 In this paper, we propose a hemispherical reconfigurable frequency selective surface (FSS) using water channels. The switching between band-pass and band-stop states is possible since the water with a high dielectric constant can control the effective ...
