Polarization converter for fixed-angle polarization deflection of electromagnetic waves in random directions

The invention discloses a polarization converter for fixed-angle polarization deflection of electromagnetic waves in random directions. The polarization converter is provided with a stereoscopic artificial electromagnetic structure for deflecting the polarization angle of the electromagnetic waves in random incident directions by fixed angles. The polarization converter comprises a total resonantarray, the total resonant array comprises 20*20 periodic resonant units which are regularly arranged along orthogonal directions, each resonant unit comprises a first column, a second column, a metalfoundation plate and insulator Teflon, the first column comprises a front section, a middle section and a rear section, the front section and the middle section are arranged in an L-shaped manner, therear section is perpendicular to a plane with the front section and the middle section and connected with the tail end of the middle section, the first column and the second column are the same in size and arranged in symmetri
