Study of Printing Errors in Digitally Fabricated FSS [PDF]

, 2013
Low cost fabrication techniques might give rise to defects in electromagnetic structures. This paper investigates the detrimental effect of producing frequency selective screens with differing percentages of absent square loop elements. It is shown that

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

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

Convoluted double square: single layer FSS with close band spacings [PDF]

, 2000
A novel element provides reflection band ratios as low as 1.1. It is derived from the double square but is less demanding on printing definition. Together, the two elements offer increased flexibility in Frequency selective surface design for close band ...

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 ...
