CohnCurrentDistribution

class pmrf.models.components.lines.stripline.CohnCurrentDistribution

Cohn’s stripline current distribution.

Mathematical Formulation

Cohn gives conductor attenuation per unit length. Inverting

\[\alpha_c=\frac{\Re(Z_s k_c)}{2\Re(Z_c)}\]

gives the geometry weight

\[k_c=2(\alpha_c/R_s)\Re(Z_c).\]

The model assigns zero conductor-loss weight when the strip thickness is unspecified.
