A nonuniform transmission line code for pulsed power Z-pinch drivers

A mathematical expression of the output voltage from a nonuniform line was deduced by investigating the transient response of a cascaded multiple-section line to an input voltage of half-sine shape that is close to the wave shape of the pulse voltage for Z-pinch. The correctness of the mathematical expression was verified by comparing the result from the mathematical expression with that from circuit simulation using PSpice code. Based on this mathematical expression, a code was wrote using MATLAB to calculate the output voltage from a nonuniform line. To make our code friendly to users, a graphical user interface was designed using MATLAB.
