Switchable Frequency Selective Surface for Reconfigurable Electromagnetic Architecture of Buildings

A Compressible Reconfigurable Frequency Selective Surface

Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

Switchable Split-ring Frequency Selective Surfaces

Abstract—Tunable frequency selective surfaces (FSSs) based on split ring resonators (SRRs) are presented. Tuning performance is achieved by means of several on/off switches placed between the rings of each SRR element. The band-stop FSS response is dynamically tuned to different frequency bands at different switching states. In addition, loadings placed at the corners of outer ring elements, fo...

A Frequency Reconfigurable Monopole Antenna with Switchable Symmetric Slot Strcture

In this paper, a novel compact frequency-reconfigurable monopole antenna with switchable symmetric slot structure is presented. The frequency-reconfigurable capability of the antenna is achieved by using a switchable slotted structure on the ground plane. The designed antenna has a simple structure and compact size of 40X40 mm . The antenna, which supports most applicable frequency bands above ...

A New Implementation of Frequency Selective Surface Cloak for Cylindrical Structures

The main purpose of this paper is to design, implement and measure a new sample of mantle cloak. A new method called mantle cloak is introduced by cloaking an object by a single, conformal meta-surface which can drastically suppress the scattering of the desired object. In this paper, a grid lattice is placed around a dielectric object as the cloaking structure. Previously, this FSS has been ut...
