A novel frequency‐selective surface, CHIRO‐FSS
Microwave and Optical Technology Letters, 1995AbstractA new frequency‐selective surface (FSS), chiro‐FSS, consisting of an infinite, periodic array of conducting elements printed on an isotropic chiral slab is proposed and analyzed. For the purpose of illustrating the properties of the chiro‐FSS, the reflection characteristics of a two‐dimensional array of crossed dipoles and circular rings backed

A novel dual-band frequency selective surface (FSS)
2009 Asia Pacific Microwave Conference, 2009A single-layer frequency selective surface (FSS) is developed with electrically small elements and two tunable passbands for WLAN application. Each FSS unit consists of a loop wire in the top metal layer and its complementary etched in the bottom metal layer, which can provide two transmission poles separated by a transmission zero.

CLD-Based Automatic Frequency Selective Surface (FSS) Inverse Design
2024 IEEE International Symposium on Antennas and Propagation and INC/USNC‐URSI Radio Science Meeting (AP-S/INC-USNC-URSI)This work presents a deep learning-based method for the inverse design of stopband frequency selective surfaces (FSSs) with the CNN-LSTM-DNN (CLD) model. With the designed model, we can directly obtain the structure geometric parameters by inputting the CLD model with stopband FSS’s Sparameters. Two cases of Jerusalem stopband FSS validate the proposed

Collision Detection by Use of Frequency Selective Surface (FSS)
2020 4th International Conference on Electronics, Communication and Aerospace Technology (ICECA), 2020Daily mortality due to motor vehicle accidents is a cause of concern as there is a shift from manually driven automobiles to completely autonomous driving vehicles. Collision between two or more vehicles is one of the most common accident that occurs every day.

On a polarization‐independent frequency‐selective surface (FSS)
Microwave and Optical Technology Letters, 2004AbstractThe frequency‐selective property of an array of rectangular microstrip elements that are resonant at a single frequency and show polarization independency is investigated both theoretically and experimentally. Investigation of the conventional frequency‐selective surface (FSS) of an array of rectangular microstrip patches resonant at a single ...

Fabrication of fabric based Frequency Selective Surfaces (FSS)
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014Three examples of Frequency Selective Surfaces (FSS) realized from conducting yarns and bare copper wire on textiles are considered. The FSS arrays are produced using the techniques of weaving, handlooming, and embroidery. There is good agreement between predicted and measured transmission responses of a rectangular loop FSS structure, and for ...

Towards Conformal Woven Frequency Selective Surfaces (FSS)
2015 Loughborough Antennas & Propagation Conference (LAPC), 2015One outstanding feature of a conformai array or periodic surface is its ability to conform to a surface whilst maintaining the operational electromagnetic characteristics. A simple textile Frequency Selective Surface (FSS), fabricated using weaving technique has been evaluated in terms of its transmission properties on a flat surface and curved ...
