A Simple Equivalent Circuit Approach for Anisotropic Frequency-Selective Surfaces and Metasurfaces [PDF]
IEEE Transactions on Antennas and Propagation, 2020 An equivalent circuit (EC) model for the frequency-selective surfaces (FSSs) comprising anisotropic elements is presented. The periodic surface is initially simulated with an arbitrary azimuthal incidence angle, and its surface impedance matrix is ...

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

Frequency and polarisation selective surface for sub‐millimetre wave atmospheric remote sensing
IET Microwaves, Antennas & Propagation, 2023 A novel Frequency and Polarisation Selective Surface (FPSS) is proposed, which separates two adjacent bands with a narrow transition zone by the staggered separation scheme and is suitable for atmospheric remote sensing.

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 ...

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
