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

Abstract We explored the thermal power radiation spectrum ρ (ω, T) of electromagnetic in a 1D photonic periodic structure combining Si and Sio 2 with truncated media an absorbing substrate. A theoretical model based on transfer matrix for both normal oblique incidence angles together Kirchhoff’s second rule is used to predict spectrum. In order study spectra, we TE TM modes truncation parameters mid, left, right gap frequencies, which correspond mid-gap temperatures. Layers n &n B are B’s indices considered be constant controlled these modes.
