FREQUENCY UPSHIFTING BY AN IONIZATION FRONT IN A MAGNETIZED PLASMA

The interaction of a light wave with a relativistic ionization front i n the presence of an applied DC magnetic field which is perpendicular or parallel to the incident wave is considered. In both cases, four tr ansmitted modes are generated in the magnetized plasma by an incident linearly polarized wave. The frequency upshifts of the various modes a re calculated and compared to the unmagnetized case. The corresponding reflection and transmission coefficients are also obtained. Finally, the density ripple associated with the free streaming mode in a magnet ized plasma for the perpendicular case is discussed.
