A simple electromagnetic shock wave analysis using boundaries in a moving frame of reference

The propagation of a planar shock wave in a lossless nonlinear magnetic medium is treated with certain idealizations. Considering a monotonically increasing pulse input, a simple formulation is given for the calculation of shock velocities and shock discontinuities. Field profiles are obtained with procedures very similar to those of linear media with fixed discontinuity surfaces. The implications of the broad assumptions used are briefly discussed.
