Abstract
Wideband wire-grid polarization rotators often used in antennas. The calculation of scattering characteristics is an actual problem. Becauseof finite dimensions of polarizers, this calculations are difficult. The simplification of calculation process is an important and actual problem.

Abstract
Self-complementary metasurfaces have gained significant attention due to their unique frequency-independent transmission and reflection properties and the possibility of the polarization transformation of plane waves. In this paper, we focus on the near-field spectrum to investigate, both theoretically and experimentally, the properties of surface waves supported by anisotropic self-complementary metasurfaces. We discover several related features, namely all-frequency hyperbolicity, extreme dual-directional canalization and TE-TM polarization degeneracy.
