Circuit 5: Transmission Line Inverter

The following file simulates a transmission line inverter. Two transmission line elements are required since two propagation modes are excited. In the case of a coaxial line, the first line (t1) models the inner conductor with respect to the shield, and the second line (t2) models the shield with respect to the outside world.
