Study of radiation power spectra in the 1-D photonic periodic dielectric structure

Abstract

Abstract We explored the thermal power radiation spectrum ρ (ω, T) of electromagnetic radiation in a 1D photonic periodic structure combining Si and Sio2 with truncated Sio2 media and an absorbing substrate. A theoretical model based on a transfer matrix for both normal and oblique incidence angles together with Kirchhoff’s second rule is used to predict the thermal radiation power spectrum. In order to study the radiation spectra, we used the TE and TM modes with truncation parameters and incidence angles in the mid, left, and right gap frequencies, which correspond to the mid, left, and right mid-gap temperatures. Layers nA&nB are A and B’s indices are considered to be constant and controlled in these modes.
