Propagation of Oblique Electromagnetic Waves Through a Warm Plasma Slab With Normal Magnetostatic Field

Abstract

Reflection, transmission, and absorption coefficients for oblique electromagnetic waves with parallel polarization incident on a warm plasma slab with a static magnetic field normal to its boundary, are studied. The effect of variation in the angle of incidence, the static magnetic field, the slab width, the plasma temperature, and the collision frequency on the various coefficients is shown graphically. It is found that the transmission coefficient increases with an increase in the plasma temperature. A change in the magnetostatic field strength decreases the transmission coefficient in one frequency region while it increases it in the other. For wave frequencies greater than cyclotron frequency, a sharp cutoff phenomenon occurs in the reflection coefficient at some angle. The absorption coefficient is found to be greater for larger slab width, except at a small frequency region where it shows oscillations.

“…Hence, normal boundary conditions are not independent but are assured to be satisfied when the tangential boundary conditions are satisfied [14]. Using a scalar electron pressure, hydrodynamic approach, it is assumed that the electron velocity normal to the plasma/ dielectric boundary is zero Chawla [15], Crawford [8] and Vandenplas [16], which results in two more boundary equations. However, we do not assume electron pressure to be zero at the boundaries.…”

“…linear and nonlinear effects. Theoretical studies using the linear small signal theory have been made on the reflection, transmission and absorption spectra [Chawla et al, 1967;Unz, 1963Unz, , 1965French et al, 1961;Zivanovic et al, 1964]. Of practical importance is the propagation of radio waves in the ionosphere, space plasmas, and transmission of light through laser produced plasmas.…”
