Study of the eigenwaves of a coplanar transmission line using the method of partial operator inversion

We propose a partial inversion procedure for the Cauchy singular integral and the integral with a logarithmic singularity determined on a finite set of bounded intervals. On the basis of this procedure, we constructed an electrodynamic model of a shielded coplanar transmission line (CTL). The results of calculation of the spectral characteristics and eigenwave field distributions of this structure are presented and the data on convergence of the approximate solution are given.
