Application of method of characteristics to IEMP cable response
Systems studies of IEMP effects on extended conductors often-times are facilitated when the excitation region can be represented by a Norton (Thevenin) equivalent circuit. One example of an extended conductor, namely, a coaxial cable, which is subjected to a spatial and time varying gamma ($gamma$) ray environment following a nuclear burst is considered. Since, in general, the $gamma$-induced cable dielectric conductivity and air conductivity in air gaps throughout the cable vary in space and time according to the $gamma$-intensity along the cable, the transmission line equations are with space and time dependent parameters and distributed excitation. The Method of Characteristics (MOC) which is employed to solve this problem for a typical coaxial cable is described in detail; the results are used to predict when a Norton equivalent circuit can be employed in systems problems.
