Magnetosonic Instability with Radiation Impact in Semiconductor Plasma

Abstract

In this promised study, we have used the multi-fluid model to investigate the instability of magnetosonic waves. Magnetosonic waves are low frequency electromagnetic waves which propagate across the applied magnetic field. These waves are longitudinal waves which are induced by compressions and rarefactions of B0 rather than the motion of charges along the electric field. A magnetosonic waves propagate with Alfven speed and fall in the category of the electromagnetic modes. We have considered the impact of thermal pressure and the impact of radiation pressure. We have elaborated the dispersion relation graphically for the case of semi-conductor plasmas where electrons and holes are treated as two fluids. In the fluid model the terms regarding radiation pressure have been incorporated in the equation of motion to observe its impact on the magnetosonic waves which when coupled with curl equation derived the dispersion relation. For numerical analysis MATHEMATICA has been used.
