Two one-dimensional computer codes have been developed to study the passage of long intense microwave pulses through the atmosphere and SF/sub 6/. The objectives are to obtain information about the electron conductivity and density as well as plasma frequency during the passage of microwave pulses in such media. In the computer model, electrons are treated as a fluid, and their effect on the passing microwave pulse are determined via the simultaneous solution of Maxwell's equations and the electron fluid equations. The model should give fairly accurate predictions, because it takes into account such variables as ambient electron density, beam intensity, ionization (avalanche) and attachment rates, and pressure. 2 refs., 7 figs.
