Verification of novel extended mixed-mode S-parameters on three-conductor lines

The novel extended mixed-mode S-parameters of the three-conductor lines are proposed in this paper based on the mode analysis. The extended mixed-mode S-parameters do not contain the cross-mode S-parameters due to the independent differential-mode and common-mode analysis. In addition, two new conversion matrices containing the current division factor are also proposed to convert the extended mixed-mode S-parameters to the standard S-parameters. Finally, the validity of the proposed theory is verified by the EM simulations of a shielded cable.
