Beam deflection and splitting using transformation optics

We propose a scheme to achieve beam defecting and splitting using a method of embedded coordinate transformation [1]. In this method one boundary of transformation region is not involved in the transformation, which means beam defecting and splitting can be realized by changing the geometric construction. Although there is a discontinuous boundary, the impendence is matched between transformation media and surrounding media according to the conventional transformation optics. Full-wave numerical simulations further verify the theoretical analysis.
