色散手征介质 FDTD分析的 New mark 方法
FDTD formulation for dispersive chiral media using the Newmark algorithm
摘要
Abstract
An explicit iteration finite‐difference time‐domain (FDTD) formulation ,based on the Newmark algorithm , for dispersive chiral media is developed and presented . The auxiliary differential equations in terms of four intermediate variables , which are defined according to the media parameters of dispersive chiral media , are established . Then the classical Newmark algorithm is introduced in discretizing the auxiliary differential equations . Finally , combining with the constitutive relation and Maxwell's curl equations , the Newmark‐FDTD formulation for dispersive chiral media is developed . The reflection and transmission coefficients including co‐polarization and cross‐polarization of a dispersive chiral slab and the bistatic radar cross‐section of the dispersive chiral sphere are simulated , with the validity and feasibility performed by comparing the results with those based on the exact solutions .关键词
