Temperature Effects on the Beat Heating of a Collisional Magnetoplasma

Abstract

The beat heating of n mngneto-plasma by two antiparallel electromagnetic waves a t different temperatures is examined. The effects of plasma temperature, plasma electron collisions, plasma ion collisions and magnitude nnd direction of the magnetic field on the excitation of plasma electron \vaves and plasma ion waves are. studied. A formula for the power absorption density of the plasma by "sing Maxwell's equations in conjuction with continuity and momentum equation, including collisions and pressure tensor terms, is derived. The contribution of the plasma temperature to the power iibsorption density, both at low and high beat frequencies, of the collisional and the noncollisional magnetised plasmas is found very significant and is illustrated numerically. The inclusion of pressure tensor term in the momentum equation is also found to cause characteristic changes in the power absorption density of the plasma with the orientation of magnetic field.
