Abstract :
The non-orthogonal coupled mode theory is extended to the analysis of multi-conductor transmission lines by including the backward wave coupling. Scattering parameters can be obtained directly from the coupled mode analysis. The eigenmode field and current are calculated using the finite difference time domain (FDTD) method, which can provide a wide band solution through a single simulation. Numerical results for the case of two identical coupled lines are presented and compared with those from ADS Momentum.
