Paper Abstract

Study of structures that demonstrate negative refraction is important in the search for metamaterials suitable for imaging capabilities below the diffraction limit. In this work, we study negative refraction behavior for the third photonic band of two dimensional elliptical rod photonic crystals in a centered rectangular lattice in air background using analysis of the equifrequency contours of this band combined with FDTD simulations. Hyperbolic equifrequency contours on the third photonic band indicate both negative and positive refraction at different angles. FDTD simulations are used to verify negative and positive refraction in the third band and search for potential imaging capabilities. If these behaviors are found, this photonic crystal design could potentially find use in sub-diffraction limit imaging applications.
