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.
