OMNI-DIRECTION REFLECTION IN ONE DIMENSIONAL PHOTONIC CRYSTAL

Abstract

Abstract—It is well known that under certain conditions, one dimensional photonic crystal (1D-PC) displays total omni-directional reflection (ODR) band gaps. The enhancement of total omnidirectional reflection band gap in 1D-PC is calculated theoretically. Using Transfer Matrix Method (TMM) and Bloch theorem, the reflectivity of one dimensional periodic structure for TEand TM-modes at different angles of incidence has been calculated. 134 Srivastava et al. 1.
