New UWB Shielding with Frequency Selective Surfaces

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 ...

All-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...

Miniaturized-Element Frequency Selective Surfaces

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...

Wavelength-selective directional coupling with dielectric-loaded plasmonic waveguides.

We consider wavelength-selective splitting of radiation using directional couplers (DCs) formed by dielectric-loaded surface-plasmon-polariton waveguides (DLSPPWs). The DCs were fabricated by depositing sub-wavelength-sized polymer ridges on a gold film using large-scale UV photolithography and characterized at telecommunications wavelengths with near-field microscopy. We demonstrate a DLSPPW-b...

Artificial magnetic conductors realised by frequency-selective surfaces on a grounded dielectric slab for antenna applications

New designs of artificial magnetic conductors (AMC), including hard and soft surfaces and dual-polarised high-impedance surfaces are realised by printed dipole/slot frequency-selective surfaces (FSS) implemented on a grounded dielectric slab. Multiband designs of hard and soft surfaces are proposed based on the use of FSS structures with different resonance lengths and orientation of dipoles/sl...
