Modification of Planck blackbody radiation by photonic band-gap structures

Abstract
We discuss a simple one-dimensional (1D) model of the modification of Planck blackbody radiation by photonic band-gap materials (PBG’s). The model gives qualitative predictions for the thermal power spectrum of 2D and 3D PBG structures, and quantitative results for 1D, distributed Bragg reflecting PBG thin films.
