The generalized method of characteristics for waveform relaxation analysis of lossy coupled transmission lines

The transient response of lossy coupled transmission lines is simulated by iterative waveform relaxation analyses of equivalent disjoint networks constructed with congruence transformers, fast-Fourier-transform waveform generators, and characteristic impedances synthesized by the Pade approximation. A two-order reduction of central-processing-unit time and a one-order savings in computer memory have been achieved. A lossy directional coupler is simulated for illustration.<
