Abstract
A model technique in time domain for the FDTD-Diakoptics was proposed. Based on modal functions in time domain, which are formed according to geometries of structures, a microwave circuit is equivalent to a multimode circuit. Full-wave analysis method is used to get the time domain responses of the multimode circuit. Fourier transfer technique is employed to obtain the impulse responses. The multimode circuit is equivalent to a multi-port circuit and the FDTD-Diakoptics is applied to analyze whole circuit. Some rules about the excitation of full-wave analysis were given and the bandwidth for inverse Fourier transform in calculating impulse responses of time-domain modes was discussed. The approach was verified by a waveguide bandpass filter.
