针对FDTD方法中多项德拜或洛伦兹色散的数值处理，提出了三种新的简单有效的算法。该公式是基于辅助微分方程，但需要比公布的计划少得多的操作。该方法在内存和计算开销方面与最好的高阶递归格式等价，但没有线性假设。
Three new simple and efficient algorithms are proposed for the numerical treatment of the multi-term Debye or Lorentz dispersion in the FDTD method. The formulation is based on the auxiliary differential equation, but requires much fewer operations than the published schemes. The approach is equivalent to the best higher order recursive schemes in terms of memory and computational expense, but without the linearity assumptions.
