New UWB Shielding with Frequency Selective Surfaces
Authors
Abstract:
In this paper a Frequency Selective Surface (FSS) as a UWB electromagnetic shield is introduced. The proposed FSS comprises a quasi-J.C-Jerusalem Cross- and a copper ring, which are located at both sides of a FR4 substrate and can represent a S.E -Shielding Effectiveness- better than 20dB in 90% bandwidth of Ultra Wide Band frequency. This structure is compact and thin. Each cell comprises J.C elements and a ring at two sides of a FR4 board with 3.2mm thickness, dielectric constant of 4.4, and loss tangent of 0.02. The structure has a 24×36 elements with dimensions of 288×432mm. Also the simulation and measurement results are in good agreement.

Frequency Selective Surfaces with Nanoparticles Unit Cell
The frequency selective surface (FSS) is a periodic structure with filtering performance for optical and microwave signals. The general periodic arrays made with patterned metallic elements can act as an aperture or patch on a substrate. In this work, two kinds of materials were used to produce unit cells with various patterns. Gold nanoparticles of 25 nm diameter were used to form periodic mon...

This article presents an overview of the progress made in the design of surface topology, fabrication, and applications of a new class of spatial filters known as miniaturized-element frequency selective surfaces (FSS’s) in recent years at the University of Michigan. The research in designing the new class was initiated with the demand for FSS’s with overall small dimensions for low frequency a...

A compact, low profile, dual polarized, ultra wideband, frequency selective surface is proposed. It is designed by using two similar metallic array structures separated by dielectric material FR4. The simulated reflection bandwidth (with transmission < −20 dB) for TE incident wave is 8 GHz from 2.87GHz to 10.87 GHz corresponds to 116%. The unit cell dimension and periodicity are of the order of...

Abstract—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. In addition, loadings placed at the corners of outer ring elements, fo...
full textPolarized infrared emission using frequency selective surfaces.
An emission frequency selective surface, or eFSS, is made up of a periodic arrangement of resonant antenna structures above a ground plane. By exploiting the coupling and symmetry properties of an eFSS, it is possible to introduce polarization sensitive thermal emission and, subsequently, coherent emission. Two surfaces are considered: a linearly polarized emission surface and a circularly pola...
full textAll-dielectric Frequency Selective Surfaces with Few Number of Periods
All-dielectric frequency selective surfaces (FSSs) can serve as an alternative to their metallic counterparts when they must operate at very high power, loss must be minimized, or when the surface itself must be low observable. When metals are avoided, there is a weaker interaction with electromagnetic waves and it becomes more difficult to achieve strong suppression in the stop band while also...
