Abstract : Solutions to the steady-state jump equations are obtained for a normal ionizing shock wave propagating into a non-conducting, quiescent gas in an electromagnetic field. Comparison of these solutions to pure MHD shocks and ordinary gas shocks indicates that ionizing shocks are hybrids having some properties common to both MHD and gas shocks. Some completely novel effects are produced by the upstream electromagnetic field. A modified Rankine-Hugoniot function is derived and used to select physically reasonable shock solutions. Solutions analogous in some respects to detonation-deflagration waves have been found, and the Chapman-Jouquet condition is applied to them. The complete boundary value problem is solved numerically in the context of an electromagnetic annular shock tube. Solution of the boundary value problem places the analytic results in the framework of experimentally observable phenomena and emphasizes the differences between ionizing shocks and MHD or gas shocks.
