N2 - 3umerical calculations have been done to determine αTHS, the total hemispherical solar absorptivity, and εTH, the total hemispherical emissivity in the infrared, of selective surfaces composed of a dielectric film on a metal substrate. The selectivity of the surface as a function of n ̂L = nL + ikL, the refractive index of the film, is discussed, as well as the effect of grading the index of the film. It is concluded that the most effective film is one having nL as close to unity as possible through its entire thickness while kL increases from zero at the front surface to a larger value at the back surface.
