Abstract

The heating of a plasma by stimulating plasma electrons as well as plasma ions with two anti‐parallel electromagnetic waves under the influence of a uniform static magnetic field is studied using Maxwell's equations and equations of motion. A formula for the power absorption per unit volume of the plasma is derived and effects of collisions and magnitude and orientation of the magnetic field on the beat heating are examined numerically. It is observed that the average power absorption in the absence of ion‐neutral collisions in the plasma barely exceeds unity in the units of pure Langmuir mode excitation where as in the presence of ion‐neutral collisions the power absorption immediately shoots up to a very high value.
