Beam Steering at Higher Photonic Bands and Design of a Directional Cloak Formed by Photonic Crystals

Abstract

Beam steering due to anomalous dispersion at higher photonic bands in dielectric photonic crystal is reported in this work. Based on this concept, directional cloak is designed that conceals a larger dimensional scattering object against the normal incident, linearly polarized electromagnetic waves.
