Novel Design of an Anisotropic Dielectric Lens with Spatially Discontinuous Boundary Based on Quasi-Conformal Transformation Electromagnetics

In this paper, a novel design of an anisotropic dielectric lens is presented. A coordinate transformation with the spatially discontinuous boundary for lens operation is proposed taking into account additional phase rotations at the spatially discontinuous boundary. The anisotropic dielectric lens is recursively designed based on the quasi-conformal coordinate transformation. The lens operation is confirmed by numerical simulations and the design validity is confirmed.
