Metamaterials are artificial media designed to achieve exotic electromagnetic responses that are not available in conventional materials. Engineering the black body thermal emission using metamaterials promises to impact a variety of applications involving thermophotovoltaics, energy management and
coherent thermal sources. Metamaterials with hyperbolic dispersion exhibit a broadband singularity in the bulk photonic density of states, which can be thermally excited and utilized in various thermal applications. In this report, we give a detailed account of equilibrium and non-equilibrium
reflection or material absorption leads to a finite quality factor of all resonances. Here we report on our result that evanescent waves can lead to both a phase and amplitude balance causing an ideal and Fabry-Perot resonance condition in spite of material absorption and non-ideal boundary discontinuities
