%X A fast generalized algorithm for 5 parameter extraction of 3-D microwave structures is presented based on the 3-D FDFD (Frequency Domain Finite Difference) method in conjunction with the asymptotic waveform evaluation (AWE) technique. In the AWE technique, the electric field strength at the input and output ports are respectively expanded in a Taylor's series around a frequency within the desired frequency band, and the coefficients of the Taylor's series are matched via the Pade approximation to a rational function and the robust Singular Value Decomposition (SVD) technique is employed while solving the Pade equation. Using the rational function, the electric field strengths at the input and output are obtained at any frequency within the desired frequency band, which is used to calculated the 5 parameter. A good agreement between the numerical results and the reported data is observed. Compared with the traditional FDFD, the computational efficiency of the present method is considerably improved.
