Polarization-Controlled Excitation of Surface Waves at Self-Complementary Metasurface

In this work, we study the surface electromagnetic waves propagating along the self-complementary metasurface. We propose a way to excite the surface waves of the necessary polarization by using the TE-TM degeneracy property of the self-complementary metasurface. In particular, we demonstrate the excitation of surface waves with linear horizontal, vertical and diagonal as well as circular polarizations. The proposed technique opens new possibilities for the in-plane signal transferring and transformation.
