Anomalous refractive indices of one-dimension absorptive plasma photonic crystal

Transfer matrix method is used to study the dispersion relations of one dimension absorptive plasma photonic crystal for both the transverse electric wave case and the transverse magnetic wave case. The effective phase index of refraction and effective group index of refraction are deduced and computed. The results show that the collision frequency impact the amplitudes of the absorption photonic band gap structure and the effective phase index of refraction especially in the lower frequency. Also, it will change the value of group index of refraction at the band edges.
