[ANGLÈS] In this project, a method for modeling multimodal circuits in a simple and reliable way is explained. This method is applicable to any transmission line with N + 1 conductors (N coupled lines plus a reference conductor). The 3D electromagnetic simulator Momentum and circuital simulator, incorporated in the Advanced Design System (ADS) software and mathematical software Matlab are used. The circuit models obtained allow to define sections of coupled lines by modal parameters and, simultaneously, analize discontinuities the circuit analized could have circuitally. For this purpose, transitional stages for transforming modal voltages and currents to circuital voltages and currents, and the other way around, are designed. The most important application presented is modal leakage measurement of circuits, in other words, use circuit models to measure how a discontinuity affects in the system modes.
