Emission and reception of Bernstein waves in the OEDIPUS-C experiment

The amplitudes of electron-cyclotron waves (ECWs, Bernstein waves) transmitted near the second harmonic of the electron gyrofrequency during the OEDIPUS-C two-point experiment were computed under particular assumptions. The current in the emitting dipole was determined by the impedance for simultaneously emitted cold-plasma ordinary-and extraordinary-mode waves. The Bernstein electric-field radiation patterns of the emitting dipole were based on the dispersion surfaces from the hot-plasma theory for tenuous magnetoplasmas. These patterns were found to have maxima close to the magnetic field axis. Computations of the receiving-dipole voltages were based on an assumption about the dipole effective length.
