Ray Optical Scattering From Uniform Reflective Cylindrical Metasurfaces Using Surface Susceptibility Tensors

A ray optical methodology based on the uniform theory of diffraction (UTD) is proposed to model electromagnetic (EM) field scattering from curved metasurfaces (MSs). The problem addressed illumination a purely reflective cylindrical MS by line source, models surface with susceptibilities and employs previously used for cylinders coated in thin dielectric layers [Kim Wang (1989)]. approach fundamentally representation using generalized sheet transition conditions (GSTCs) which characterizes terms susceptibility dyadics. An eigenfunction (EF) description derived considering both tangential normal susceptibilities, develop optics (RO) scattered fields including specular geometrical field, described creeping waves region over shadow boundary. specification dependent evaluation Pekeris caret function integral method follows RO-GSTC then successfully demonstrated variety cases independently verified rigorous EF solution (EF-GSTC) full-wave Integral Equation (IE-GSTC), entire domain deep lit shadow.
