摘      要：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.
