+* Subcircuit conv2wtwentyinch
+* conv2wtwentyinch is a subcircuit that models a 2-conductor transmission line with
+* the following parameters: l=9.13e-09, c=3.65e-12, r=0.2, g=0,
+* inductive_coeff_of_coupling k=0.482, inter-line capacitance cm=1.8e-12,
+* length=20. Derived parameters are: lm=4.40066e-09, ctot=5.45e-12.
+* 
+* It is important to note that the model is a simplified one - the
+* following assumptions are made: 1. The self-inductance l, the
+* self-capacitance ctot (note: not c), the series resistance r and the
+* parallel capacitance g are the same for all lines, and 2. Each line
+* is coupled only to the two lines adjacent to it, with the same
+* coupling parameters cm and lm. The first assumption imply that edge
+* effects have to be neglected. The utility of these assumptions is
+* that they make the sL+R and sC+G matrices symmetric, tridiagonal and
+* Toeplitz, with useful consequences.
+* 
+* It may be noted that a symmetric two-conductor line will be
+* accurately represented by this model.
