Electromagnetic Scattering Controlling for a Rectangular Groove with High Impedance Surfaces Loading
In this paper, a possible solution for controlling electromagnetic scattering from a rectangular groove is presented based on high impedance surfaces (HIS) loaded on the two sides of the considering groove. The HIS is realized by loading the H-shape frequency selective surfaces on a grounded dielectric layer, which is optimized according to the relationship between the scale parameters and its dispersion diagrams. The use of HIS resulting in a significant scattering suppression for the groove over a wide angular range for transverse magnetic (TM) polarization, and the maximum reduction of RCS can reach 17 dB compared with the original structure. Moreover, the monostatic radar cross section (RCS) reduction with the proposed method is superior to other methods such as loading resistive sheets.
