Simulation for thermal radiation emitted from functional surface

Abstract

Radiative characteristics of one-dimensional structured emitter was investigated through calculating emission of thermal radiation by solving the Maxwell's Equations using a FDTD method. The radiative simulation based on fluctuational electrodynamics enable to evaluate quantitative emission of thermal radiation. For a specular emitter made of nickel metal with a thin-transparent film, some interference was described through simulation solving emission of thermal radiation. For a shallow-grooved surface emitter made of silicon carbide, surface-phonon polaritons were coupled with a propagating-radiation by the periodic structure. Finally, the characteristics of emission controls by the specular metal with the thin-transparent film and the shallow-grooved surface emitter were illustrated and compared from a point of view of emission of thermal radiation. © 2011 The Japan Society of Mechanical Engineers.
