The properties of emissivity in one dimensional photonic crystals are studied using transfer matrix method and Kirchhoff’s second law. It is found that emissivity and its angular distribution can be controlled by truncating the first layer. It is observed that with increase in incident angle, emissivity is shifted towards lower wavelength. From the studies of angular distribution of emissivity with truncation parameter, it is demonstrated that the magnitude of emissivity can be increased with truncation parameter while maintaining the same angular lobe.
