In this letter, a low-scattering metasurface with dual-band, wide-angle, and polarization-insensitive features is proposed and validated by measurement. The metasurface converts incident electromagnetic wave into heat at S-band frequency, and disperses it into various reflected directions across X-and Ku-band frequencies. Furthermore, each operational mode works independently. The agreement between simulated and measured results demonstrates that more than 8 dB radar cross-section reduction can be realized over 3.9-4 and 7.7-19 GHz under different polarized wave incidences. The dual-band and wideband characteristics are also well maintained within 0 degrees-45 degrees oblique incidence.
