Paper Abstract

We will discuss a passive thermal emission management surface that can manipulate the direction and wavelength bands of emission. We are designing and fabricating diffractive optics in materials that support surface-polariton plasmons. We use a grating in this material to couple the thermally-generated plasmons to photons. Grating parameters, such as grating depth and duty cycle, are varied to optimize the plasmon/photon coupling efficiency. The grating configuration ensures a phased, radiative response if the plasmon decay length along the surface traverses many grating periods. All of these parameters, material indices and dimensions, determine the specular and angular "shape" of emission.
