Abstract

A novel invisible media based on transformation optics consisting of three regions to investigate invisibility was proposed here. What the media does is to compress the light to a small region so that the light can avoid interacting with objects, and then it would be recovered in the latter. Comparing with the traditional cylinder cloak, which require the light propagating around the concealed region, the media would help us to avoid singularity of material parameters. Finite element simulations for two-dimensional cases have been performed to prove these ideas.
