Phys. Rev. Lett. 93, 213905 (2004) [4 pages]Thermal Radiation from Photonic Crystals: A Direct CalculationReceived 20 April 2004; published 19 November 2004 A classical simulation of equilibrium thermal emissivity from dispersive, lossy photonic crystals is presented. Normal emission results consistent with those assuming Kirchoff's law are obtained; i.e., a photonic crystal does not emit more than what a blackbody does. Significant enhancement, however, can be achieved over the radiation intensity from a uniform slab, indicating the potential usefulness of photonic crystals in incandescent lighting and thermal photovoltaic applications. © 2004 The American Physical Society URL:
