Tai-Chi-Inspired pancharatnam-berry phase metasurface for dual-band RCS reduction

This paper presents a new metasurface inspired by Tai-Chi shape, which is applicable to dual-band radar cross section (RCS) reduction. The Tai-Chi-shape unit cell features a rotational self-complementary property. The metasurface, composed of such cells with different rotations, exhibits randomly distributed phase shift covering 2π range, giving rise to a diffusion of backscattering. Therefore, the RCS of the metasurface is substantially reduced compared to one of the equal-sized metallic plates. The full-wave simulation results show that the proposed metasurface can obtain nearly 8dB RCS reduction from 14.7GHz to 20.6 GHz and from 22.7GHz to 23.7GHz with polarization-independent performance.
