摘要

This thesis explores the thermal radiation intensity modication by photonic
crystals (PhC) when elevated to high temperatures. The modication of the density of
states by the PhC creates a band gap that suppresses thermal radiation in that frequency
band. Such suppressions lead to enhancements in radiation at frequencies outside of
the band gap. The thermal radiation spectrum can be estimated using the direct and
indirect method. The direct method involves the density of states while the indirect
method is based on Kirchho's law of detailed balance for thermal equilibrium. Both
methods are shown to be able to predict the thermal radiation power spectrum for a
one dimensional (1D) PhC. Additionally, a micro cavity three-dimensional PhC involving
a woodpile structure coupled with a 1D PhC is simulated using the software Computer
Simulation Technology (CST).
