Linearly polarized incident electromagnetic waves were propagated along the direction of a static magnetic field through a helium afterglow plasma in the frequency region of the electron cyclotron frequency. The experimental measurements illustrate clearly the behavior of the two transverse wave modes that the plasma can support. At high electron densities the right-hand circularly polarized component is completely attenuated and the variation of the transmitted signal is due entirely to the left-hand circularly polarized component. Alternately at low electron densities the plasma is transparent to the left-hand mode and the variation in transmitted signal is due to the righthand mode. Detailed comparisons of measurements of the phase and intensity of the components of the electric field transmitted through the plasma in the same orientation as the incident polarization and cross-polarized to the incident polarization show good agreement with theory.
