A full wave fast and efficient tool for mm-wave coupled lines simulation

We applied the Spectral Domain Analysis to the simulation of an arbitrary multilayer structure of coupled lines, with no restriction on the number of lines and layers. The efficiency of the algorithm allows the implementation on a PC-based platform with a reasonably short computation time. All the field quantities are available, the external matrices and a time-domain analysis is held to give diagrams of signal propagation along the lines in order to characterize the coupling effects and the undesired crosstalk. Simulation results are in good agreement with both measured data and other e.m. techniques.
