提出了TE电磁场问题的二维离散惠更斯模型或TLM仿真方法。具有可变传播速度和特性阻抗的TLM元件或节点被应用于几个实际问题，包括在墙壁边缘和周期性网格或凹槽上的散射，沿介质结构的波传播以及两个平行光波导之间的模式耦合。将TLM解与理论解或其他数值方法的结果进行了比较，得到了比较一致的结果。
The two‐dimensional discrete Huygens’ modelling or TLM simulation is presented for the TE electromagnetic field problems. The TLM element or node with variable traveling speed and characteristic impedance is applied to several practical problems including scattering at the edge of a wall and over periodic grids or grooves, wave propagation along a dielectric structure, and a mode coupling between two parallel optical waveguides. The TLM solutions are compared with the theoretical ones or the results of other numerical methods and reasonable agreement is achieved.
