Spatial Investigations of Point-Radiated Fields above the Electron Cyclotron Frequency in an Inhomogeneous Magnetized Plasma

Spatial behaviors of mode-converted electron Bernstein waves at the upper hybrid layer in an inhomogeneous magnetized plasma are investigated experimentally and theoretically when the radiated source is located outside the upper hybrid layer. The theoretical spatial field patterns in two dimensions which include the mode-converted cyclotron harmonic wave radiated from a point source are found to be in near accord with the experimental results.
