The electron plasma waves which are radiated from a point source and propagate in an oblique direction with respect to an applied static magnetic field are investigated both theoretically and experimentally. The observed phase velocities and wave amplitudes in the oblique directions are explained by considering anisotropic characteristics of a magnetoplasma in which the directions of phase and group velocities are different. The observed phase velocity in the radial direction was found to agree with the theoretical ray velocity.
