Dispersive Contour-Path FDTD Algorithm for the Drude2cp

We use the Discrete Contour Path (DCP) method to process dispersion media of any shape represented by the Drude2cp model, which can accurately calculate the coefficients of the media. And the Drude2cp model was introduced into the FDTD algorithm using the trapezoidal recursive convolution (TRC) method. The obtained method has higher accuracy compared to the analytical method.
