Abstract: | We have studied absorption and thermal radiation for a three dimensional lossy photonic crystal of dielectric spheres by using a multiple scattering method. It is shown that such simple structures have excellent selective thermal radiative characteristics in different photonic bands. There is stronger thermal radiation at high frequency than that at low frequency. In comparison with the uniform slab without photonic crystal structure, in the photonic band gap, the thermal emission intensity is greatly suppressed and very weak, but not zero due to the penetration depth. Under the same lattice structure, the thermal emission of photonic crystal varies with the change of the radius of the spheres. |
