We present a new numerical algorithm for the simulation of dispersive media. This model named ADETLM is based on the transmission line modeling method with the symmetrical condensed node (SCNTLM) and novel voltage sources and exploits the polarization current density J along with the voltage electric as well as the average approximation. We extend the proposed algorithm to media with dispersions described by multiple second-order Lorentz poles; the obtained results of the reflection and transmission coefficients are compared with analytical solutions.

用于Lorentz分散介质的新型ADE-TLM

我们提出了一种用于分散介质仿真的新数值算法。这个名为ADETLM的模型基于具有对称凝聚节点（SCNTLM）和新型电压源的传输线建模方法，并利用极化电流密度J以及电压电以及平均近似值。我们将提出的算法扩展到具有由多个二阶洛伦兹极点描述的色散的介质。将得到的反射系数和透射系数的结果与解析解进行比较。
