Abstract

Broadband terahertz radar cross section (RCS) reduction is achieved via a 1 bit coding metasurface. The proposed electromagnetic metasurface consists of two basic digital elements. The 180° phase difference between the neighboring elements can realize the reduction of RCS by a non directional low scattering of the broadband THz frequency. The calculated results show that the RCS reduction can be up to 15 26 dB in most of the wide frequency range of 0.7 1.6 THz. Compared to the existing research results, the metasurface for RCS reduction is non directional and has the characteristics of broad band and low scattering.
