Transmission Upper Bound of Planar Single-Layer Frequency Selective Surface

Abstract

Abstract-In this study, the transmission of planar single-layer frequency selective surface (FSS) has been studied using modal analysis method, and the maximum transmission that a planar single-layer FSS structure with an infinitely thin array can reach is presented. The results show that this transmission upper limit is independent of the array and the element, which indicates that it is impossible to achieve a transmission higher than this upper limit under a given incident and dielectric-supporting condition by the design of the periodic array. As the modal analysis method is an accurate method to solve the scattering problem of planar FSS with an infinitely thin array, this upper limit is also independent of the solution method. Results of both numerical simulations and experiments show that the upper limit presented in this paper is strict, but may be hard to attain when FSS is supported by lossy dielectric mediums.

Transmission upper limit of band-pass double-layer FSS and method of transmission performance improvement

“…They also pointed out that their analysis could be extended to any number of substrates and superstrates, but could not be extended to multiple periodic surfaces. The author of this paper discussed the maximum transmission that a single-layer metal array with an arbitrary dielectricloading form can reach in [22,23] and provided a specific transmission upper bound for single-layer FSSs. However, all of the above have not provided a perfect answer to the design problem of a complex frequency selective structure.…”

“…Recently, EBGs and PBGs are of great interest due to their extraordinary properties and potential applications, e.g., filters, polarizers, substrates for radiating elements, or optical switches [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Many numerical techniques have been utilized to investigate band gap structures.…”
