Comment on Radiative transfer over small distances from a heated metal

We show that there is no contradiction between the results presented by Pan Opt. Lett. 25, 369 (2000)] and the 1/L(2) dependence of the radiative energy flux between two half-spaces separated by a small vacuum gap of width L obtained by Polder and Van Hove Phys. Rev. B 4, 3303 (1971)] and by Loomis and Maris Phys. Rev. B 50, 18517 (1994)].
