Multiconductor Analysis

Multiconductor Transmission Line Analysis

The program CONMTL includes a method of moments (MoM) technique. After the numerical computation of the equivalent surface charge distribution, which is the solution of a system of linear equations, the per-unit-length parameters are determined. This data is the basis for a subsequent evaluation of the transmission line Y matrix.

Output:

  • Per-unit-length parameter matrices [C’], [L’] for a large variety of cross sections including substrate or dielectric coating
  • S-parameter matrices for usage in external network solvers (Touchstone format)
  • Selected S-parameters as a function of frequency
  • E field distribution in the transmission line cross section

In HDF5 format the Y matrix of the transmission line can be loaded into the network solver CONCIRC where the corresponding conductors can by terminated by lumped loads for example.
