Function to analyze the electrical characteristics of a
coupled stripline transmission line. The physical
dimensions of the coupled stripline line are given as inputs and the
characteristic impedance, effective dielectric constant, loss and
open circuit end correction are calculated.
The model accounts for dispersion (frequency dependent propagation
velocity).
