  • The setting method of time-domain excitation sources is studied in this paper in order to analyzing the characteristic of waveguide by using the Multidomain PseudoSpectral Time-Domain (MPSTD) algorithm. Based on it, a rigorous analysis for a compound slot coupler by using the MPSTD algorithm is presented. Coupling slot characteristics of half-height X-band waveguide are obtained, including the resonant length and scattering parameters in different height, offsets, and tilt angles of the slot. All numerical results indicate the MPSTD is more accurate and efficient to analyze the slot coupler. And it extends application fields of MPSTD and offers a scheme for analyzing the broad-band characteristic of complex waveguide accurately and efficiently.
