A trapezoidal recursive convolution (TRC) technique is one of the simple ways to incorporate dispersive models into the finite‐difference time‐domain (FDTD) method. The authors newly develop the TRC–FDTD method for the analysis of arbitrary‐shaped dispersive materials using a dispersive contour‐path algorithm. The accuracy of the present method is found to be the same as that using the Z ‐transform technique with reduced computational requirements.
