Data from: Ultra-wideband and polarization-independent RCS reduction based on polarization conversion metasurface
<p>We proposed an ultra-wideband polarization conversion metasurface (PCM). Because it is an anisotropic structure with a pair of mutually perpendicular symmetric axes<i> u</i> and <i>v</i>, and the phase difference between the reflection coefficients under <i>u</i>- and <i>v</i>-polarized incidences is close to 180<sup>°</sup> in an ultra-wide frequency range from 9.5 to 29.5 GHz, it can realize ultra-wideband circular polarization (CP) maintaining reflection and make its co-polarized reflection coefficient under CP incidence close to 1.0 in the ultra-wide band 9.2-29.7 GHz. In addition, when its unit cell structure is rotated by an angle <i>ψ</i>, almost ±2<i>ψ</i> Pancharatnam-Berry (PB) phase will be generated in co-polarized reflection coefficient under CP incidence. Thus, based on the proposed PCM, an ultra-wideband Pancharatnam-Berry (PB) 2-dit coding metasurface is conveniently proposed. The simulation and experimental results show that the coding metasurface can achieve more than 10 dB radar cross section (RCS) reduction in the ultra-wide frequency band 8.7-29.3 GHz with a relative bandwidth of 108.4% under normal incidence with arbitrary polarizations, in addition, when the incident angle is increased to 30<sup>°</sup>, the RCS reduction performance can be kept well. In this data file, the simulation results obtained by commercial software Ansys HFSS and measurement results are listed.</p>
