Structure of the compressed layer of gas behind one-dimensional time-dependent large-amplitude waves moving across a collisionless fully ionized magnetic plasma is studied by means of electronic computer codes developed by Auer, Hurwitz, and Kilb. Data from these codes are processed by an automatic digital-to-analog plotter and presented graphically in several formats that make it possible to observe special characteristics of the development of collisionless shock waves.nCases considered in the first sequence of solutions illustrate the variation of the structure of the flow field with Alfven Mach number of the shock front. Changes brought about in these flow fields when the driving and ambient magnetic fields are assumed to be of opposite sign are then studied. Wave forms that result when two identical collisionless shock waves collide are presented for two special situations. The effect of the mass ratio of the two charged species and the temperature of the ambient plasma on the structure of the magnetic field in the flow field is also considered.
