Loaded-frequency selective surface

Frontiers of Electrical and Electronic Engineering in China, 2005
AbstractIn this paper a new frequency‐selective surface (FSS) with loadings, is introduced and analyzed using period moments methods. The simulated results show that FSS may operate in different bands and especially generate a large reduction in the resonant frequency for a fixed unit‐cell size through different loadings.

Miniaturized frequency selective surface and broadband frequency selective surface design

2016 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2016
This paper presents the results of our research in the field of frequency selective surface in recent years. Aiming at the traditional passive frequency selective surface (FSS) in this paper, we mainly do two aspects of research work, which is the research of the small frequency selective surface and the research of the ultra wide band frequency ...

Design of a Frequency-Tunable Frequency-Selective Surface with High-Selectivity

2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020
In this paper, a novel two-layered tunable Frequency-Selective Surface (FSS) with high-selectivity is presented. GaAs flip-chip varactors are also introduced in each unit-cell to achieve the frequency tunable capability and meanwhile maintaining lower insertion loss.

Conformal frequency selective surfaces design

2016 24th Signal Processing and Communication Application Conference (SIU), 2016
In this study a conformal frequency selective surface has been proposed for 5.8GHz frequency band and compared with a planer array frequency selective surface in the same sizes. A satisfactory performance has been obtained and a negligible difference has been obtained in terms of frequency and bandwidth when compared to the planer one.

Analysis of Curved Frequency Selective Surfaces

2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007
This article presents the full-wave analysis of frequency selective surfaces (FSS) embedded in a multilayer spherical supporting structure. The FSS are composed of circular ring elements because of its good polarisation properties and insensitivity of the resonant frequency on the angle of the incident plane wave.

Nanophotonic Frequency Selective Surfaces

Frontiers in Optics, 2005
The near-infrared properties of metallic films perforated with periodic arrays of annular apertures are considered computationally and experimentally. The transmission spectrum is investigated theoretically in the context of the near-zone electric and magnetic fields.

Broadband Frequency Selective Surface

MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's, 1986
Future communication satellites will use dichroic subreflectors to produce multiple focal regions from a single parabolic reflector. This additional focal region will allow for beams operating over different frequency bands to be produced by a single reflector and avoid the feed crowding or mechanical limitations current reflector antennas encounter ...

Plasma Frequency Selective Surfaces

IEEE Transactions on Plasma Science, 2007
This paper is focused on using plasma as a substitute for metal in a frequency selective surface ("FSS"). FSSs have been used for filtering electromagnetic waves. Each FSS layer has to be modeled using numerical methods, and the layers are stacked in such a way to create the desired filtering.

Complementary frequency selective surfaces

IEE Proceedings - Microwaves, Antennas and Propagation, 2000
A concept in frequency selective surface (FSS) technology that stems from Babinet's principle, whereby a hybrid of two closely coupled FSS, a layer of conducting elements and a layer of aperture elements are etched either side of a dielectric substrate, acronymed as complementary FSS (CFSS) is introduced.
