Radiated-Emission Analysis of Electrical Interconnection Structures based on a Modal Network Model

A novel method for calculating the radiated far field of electric interconnection structures based on an equivalent modal network model is presented. From the amplitudes of the current modes in the system, as obtained by circuit simulation, the radiated field is set up as linear combination of the corre-sponding radiation modes. This enables an efficient broadband simulation of the radiation of interconnection structures with different, linear loads, facilitating the optimization with respect to the electromagnetic compatibility (EMC) of the system. The proposed method is validated in the frequency domain by comparison with Full-Wave reference results.
