Analysis of a joined split-ring FSS structure characterized by three resonant frequencies and a tuned enhanced band using the WCIP method

Abstract

Abstract:This work presents the analysis of a joined split-ring frequency selective surface (FSS) for X-band applications using the wave concept iterative procedure (WCIP). When the incident normal plane wave is polarized in the x direction, the joined split-ring FSS shows three rejecting bands at 9 GHz, 10.5 GHz, and 11.5 GHz simultaneously with bandwidths of 3.11 GHz, 0.6 GHz, and 1.13 GHz, respectively. Moreover, one rejecting band at 6.5 GHz is present when the FSS is fed with a normal plane excited in the y direction. In addition, the different resonant frequencies can be tuned independently to give rise to a tuned enhanced band. An FSS with four rejecting bands is obtained when the metallic notch is placed on the lower coupling metallic strip. The joined split-ring FSS is manufactured and measured. The simulated results obtained using the WCIP are compared to the measured results and COMSOL Multiphysics results and good agreement is obtained.

Characterization of Switchable Rectangular Ring FSS with Non Coupled Parallel Metallic Strips for Multi Band and Dual Polarized Applications Using WCIP Method

“…In concentric rectangular rings FSS the insertion of one more ring results in the addition of one resonant frequency in both perpendicular directions. To decrease the metallic surface of the FSS maintaining the multi band and dual polarization characteristics the quasi-rectangular open-rings is introduced [5], [6], [7], [8], [9]. In the U-shaped FSS the two resonant are controlled by the strips lengths [5].…”

WCIP Method Applied To Modeling an L-Notched Rectangular Metallic Ring FSS for Multiband Applications and its Equivalent Structure

“…For the last few decades, FSS are one of the important planar periodic structures, which are investigated and characterized in several important applications domain such as electromagnetic engineering and microwaves. Due to large demands for multi-functionality of FSS in electrical engineering and telecommunications, many researchers studied and developed the FSS for designing multiband responses [3]- [15].…”
