描述了一般色散介质中电磁场时域有限元建模的一般公式。该公式基于二阶矢量波动方程，并通过递归评估的卷积积分结合了介质的色散效应。在每个时间步长内使用线性插值，该评估的精度保持在二阶。给出了数值例子来验证所提出的公式。
A general formulation is described for time-domain finite-element modeling of electromagnetic fields in a general dispersive medium. The formulation is based on the second-order vector wave equation and incorporates the dispersion effect of a medium via a recursively evaluated convolution integral. This evaluation is kept to second order in accuracy using linear interpolation within each time step. Numerical examples are given to validate the proposed formulation.
