Abstract
Quasi-conformal transformation optics theory has been proven to be able to arbitrarily regulate electromagnetic waves. Especially in the case of two-dimensional TE polarization, the non-magnetic media can be used to construct the transformation space, which avoid narrowband and high loss properties of magnetic metamaterial. Based on the quasi-conformal transformation optics, the lens from transformations between virtual and physical arrays are designed in this paper. By loading the transformed lens on physical conformal and linear arrays respectively, the same radiation characteristics with the virtual arrays can be achieved in the corresponding physical spaces.
