Abstract

© 2016 IEEE. We demonstrate that self-collimation effects in the invisibility cloak medium formed from 2D dielectric Photonic Crystal (PhC) can support wave propagation along curvilinear paths around an object to be hidden, with superluminal phase velocities controlled by deformation of PhC lattice cells. These effects can be used for the development of uni-directional cloaks with wave phase preservation, which can be scaled from microwave to optical frequencies. The obtained results show that employment of self-collimation effects can make PhCs advantageous with respect to metamaterials at the formation of the media requested by coordinate transformation techniques for the development of new electromagnetic devices.
