Abstract :
Metamaterial coatings have been previously studied for their ability to tailor the dispersive IR emissivity of a surface. Here, we investigate metamaterial structures based on an electromagnetic band-gap surface for use as near-IR emitters with custom angle and polarization 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 with custom polarization.
