A relativistic fluid code for high-power microwave propagation
The propagation of a high-power microwave pulse through the atmosphere is treated with a relativistic fluid code. In this treatment, the first three moments of the Boltzmann equation are used to obtain fluid equations for electron density, mean momentum, and thermal energy. Particle, momentum, and energy exchange rates for elastic, inelastic and ionization collisions are included in the calculation. The effects of electron spatial diffusion and the ponderomotive force are contained in the relativistic form of the Boltzmann equation. For an incident plane parallel microwave pulse, the fluid equations and Maxwell's equations are solved to obtain the temporal behavior of the fields as the microwave propagates through the atmosphere. Theory and applications of the relativistic fluid code are presented.
