Spectral control of near-field radiation transfer by metal-insulator-metal structured emitters

Abstract

Spectral Control of near-field radiation transfer by Metal-Insulator-Metal (MIM) structured emitter made of Au for a thermophotovoltaic (TPV) power generation system is studied using a Finite Difference Time Domain (FDTD) method. As a result, the radiation flux was enhanced within a wavelength range from visible to a near infrared (up to about 2 microns) compared with the case of parallel plane configuration due to the electric field in the narrow channel between metal islands made of Au.
