Abstract
In this paper, a beam shifter is proposed based on the Schwarz-Christoffel (SC) mapping, which transforms a traditional Maxwell´s Fish-eye (MFE) lens to a slab beam shifter. The required refractive index distribution of the transformed slab is derived numerically from Jacobin matrix. The beam shifting effect is simulated with the full-wave software COMSOL Multiphysics for the slab with two waveguides at 180GHz. The proposed design is expected to be extended to other bands easily and also to be used as a wave component without circuit inside.
