Analytical Approach for Crosstalk Characterization of Multiconductor Transmission Lines Using Mode Decomposition Technique in the Time Domain

Crosstalk between lossless multiconductor lines is analyzed using a mode decomposition technique in the time domain. An approach that mode voltages and currents at an arbitrary point along the lines are expressed in terms of the initially incident mode sources and the mode reflection coefficients is proposed. The results obtained by the approach offer insight into how each mode component influences the crosstalk waveform. A SPICE equivalent circuit is also developed based on the approach. The validity of our approach and the SPICE model is investigated by comparing the results with those from fast Fourier transform simulations.
