RCS reduction and wave manipulation using planar phased surface

Abstract

In this paper a scheme to suppress reflection of incident wave or reduction of radar cross section (RCS) is proposed. A non-resonant modified Jerusalem type meta-atom is optimized to obtain linear phase response with several dielectric support. Simulated near-field results of a linear arrangement of phase show powerful beam steering capabilities while the random distribution of phased particles produces a diffused scattering of incident wave at three frequency samples (9.5GHz, 10GHz, and 10.5GHz). Simulated bistatic RCS patterns of linearly phased meta-atoms show powerful manipulation of the direction of maximum RCS when compared to the case of the metallic plane plate. In the case of randomly phased-surface, we demonstrated approximately 15dBsM reduction of RCS. Due to Efficient suppression of reflection and low-cost planar geometry, our work enables novel route for x-band stealth technology.
