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.

Plasma frequency selective surfaces

The 30th International Conference on Plasma Science, 2003. ICOPS 2003. IEEE Conference Record - Abstracts., 2003
Summary form only given, as follows. Summary form only given. This research is focused on using plasma as a substitute for metal in a frequency selective surface (FSS). Frequency selective surfaces have been used for filtering electromagnetic waves. Our plasma frequency selective surfaces can be tuned to a desired filtering by varying the density or ...

Plasma frequency selective surfaces

2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014
Plasma frequency selective surfaces (FSS) [1]-[2] use plasma instead of metal for the FSS elements. Frequency selective surfaces have been used for filtering electromagnetic waves and Munk [3] wrote a comprehensive book on the subject. In conventional metal FSS, each layer has to be modeled using numerical methods and the layers are stacked in such a ...

On finite frequency selective surfaces

IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004
It is customary to approximate finite periodic structures by considering infinite surfaces. While this approach works under many circumstances, there are cases where strong surface waves are excited that cannot be accounted for by the infinite array approach An explanation of this phenomenon is shown.

Limiting frequency selective surfaces

2009 European Microwave Conference (EuMC), 2009
Abstract In this paper the concept of limiting Frequency Selective Surface (FSS) is presented. The design of a reconfigurable FSS equipped with PIN diodes, aimed at the protection of a radar receiver from high power impinging electromagnetic waves is outlined and verified against the measurement results of a hardware demonstrator.

Infrared frequency selective surfaces

IEEE Antennas and Propagation Society Symposium, 2004., 2004
A frequency selective surface (FSS) is designed and fabricated to resonate in the infrared. The FSS is designed via periodic method of moments (PMM) software and is based on circuit-analog resonance of square loop elements. The lithographically composed FSS resonates at the absorption of infrared radiation.

Thick frequency selective surfaces

IEEE Antennas and Propagation Society International Symposium 1992 Digest, 1992
As an additional means of controlling bandwidth, the use of periodic screens in free space with thick metallization was investigated for single-square loop and double-concentric-square loop elements. These loops elements were chosen because the passbands of such screens, with tight lattice spacing, display a remarkable insensitivity to incident ...
