Abstract
A plasma in a magnetic field is capable of many different kinds of oscillations. The simplest of these are oscillations which propagate parallel or perpendicular to the magnetic field. In these two simple cases, in which the electric field is parallel to the magnetic field, the two modes of oscillation are uncoupled or independent. The waves that propagate parallel to the field are longitudinal electrostatic plasma oscillations; those that propagate perpendicular to the field are transverse electromagnetic waves. The magnetic field does not act on currents directed along it; therefore, it has no effect on oscillations of this kind.* Hence, it should be possible to probe a plasma with waves that propagate at right angles to the magnetic field but are polarized parallel to it.
