Temporal coupled mode theory for thermal emission from a single thermal emitter supporting either a single mode or an orthogonal set of modes

Abstract

We propose a temporal coupled mode theory for thermal emission from a single emitter supporting either a single mode or an orthogonal set of modes. This temporal coupled mode theory provides analytic insights into the general behaviors of resonant thermal emitters. We validate the coupled mode theory formalism by a direct numerical simulation of the emission properties of single emitters.
