N2 - Metamaterials have been previously studied for their ability to tailor the IR emissivity dispersion, pattern, and polarization of a surface. Here, we investigate a reconfigurable metamaterial structure based on dielectric resonators composed of phase-change material for use as near-IR emitters with custom angle selectivity. A genetic algorithm is successfully employed to optimize the metamaterial structures to have minimum emissivity in the normal direction and high emissivity at desired off-normal angles specified by the designer.
