Electromagnetic Wave Propagation and Inverse Bremsstrahlung Absorption in Suddenly-Created Plasmas.
Abstract
Electromagnetic wave propagation and inverse bremsstrahlung absorption in suddenly-created plasmas are studied in this investigation. Maxwell's equations are used to determine the Laplace transformations of the electromagnetic field expressions for plane wave propagation in a source-free region and for a general dispersion equation which relates the wavenumber k to the complex frequency s. Thus, the fields in the time domain are determined by inverse Laplace transformations using the dispersion relation that is consistent with the plasma under condiseration. The investigation considers two different plasma models. The first area of investigation involves a plasma that is homogeneous, isotropic, linear and slightly lossy. The second area of investigation involves a plasma with a magnetic field parallel to the direction of propagation of the original wave.
