Homogenous Optic-Null Medium Performs as Optical Surface Transformation

By Fei Sun and Sailing He
Progress In Electromagnetics Research, Vol. 151, 169-173, 2015


A new theory on designing electromagnetic/optical devices has been proposed, namely, a surface transformation (ST). Compared with Transformation Optics (TO), we do not need to consider any mathematics on how to make a coordinate transformation, and what we need to do is simple to design the shapes of the input and the output surfaces of the device with pre-designed functions. Unlike the devices designed by TO which are often inhomogeneous anisotropic media, all the devices designed by ST only need one homogeneous anisotropic medium (referred as the optic-null medium) to realize. Our method will lead a new way to device design without considering any coordinate transformations.
