Abstract
This paper proposed a 1-bit coding metasurface which based on polarization conversion for broadband RCS reduction. The coding metasurface were composed of digital ‘0’ and ‘1’ elements which formed by two semicircle structure and its mirror, respectively. The simulation confirmed that the unit cell can realize the polarization conversion; Moreover, the PCR was more than 90% at 7.7-18.3 GHz. Meanwhile, the phase difference of ‘0’ and ‘1’ element was exactly π at full band. So, the coding metasurface can scatter the energy of incident electric magnetic in all other directions, it successfully realized the RCS reduction.
