Surface plasmon polariton based wavelength selective IR emitter combined with microheater

A newly proposed surface plasmon polariton (SPP) based wavelength selective IR emitter is combined with microheater. The excited SPP propagates on the metallic grating carrying IR having the wavelength near to the grating pitch. By confining IR having other wavelength inside the cavity, the thermal emission is controlled. Emission peak at the wavelength near to the period of the grating is observed. Since the microheater can minimize the loss due to the thermal conduction from the high temperature region to the surrounding basement, the energy efficiently is expected.
