Perfectly Matched Layer Absorbing Boundary in Dispersive Materials and Performance Analysis

Chen Mingyang Yu Rongjin (School of Information Science and Engineering, Yanshan University, Qinhuangdao 066004)  
Based upon properties of dispersive material and theory of electromagnetic wave reflection on the interface of two materials, it is found that material dicontinuity is the cause of the invalidation of the general perfectly matched layer absorbing boundary conditions (PML ABCs) in dispersive materials. The effectiveness of dispersive perfectly matched layer absorbing boundary conditions is proved numerically, which helps to reduce computing spatial domain and calculation error of the finite difference time domain (FDTD) method.
