Analysis of Curved Frequency Selective Surfaces
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007This 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.

Broadband Frequency Selective Surface
MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's, 1986Future 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 ...

Nanophotonic Frequency Selective Surfaces
Frontiers in Optics, 2005The 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.

Plasma Frequency Selective Surfaces
IEEE Transactions on Plasma Science, 2007This 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.

A Dual-Plane Beam-Sweeping Millimeter-Wave Antenna Using Reconfigurable Frequency Selective Surfaces
IEEE Antennas and Wireless Propagation Letters, 2018In this letter, a dual-plane beam-sweeping dielectric resonator antenna (DRA) using cantilever enabled frequency selective surfaces (FSSs) is presented. The proposed antenna consists of a conventional cylindrical DRA and a hexagonally arranged active FSS
