Excitation of the Magnetospheric Cavity

Abstract

Stanford University carried out a detailed study of the following topics: 1) the optimum orbit for exciting the magnetospheric cavity resonance by a space-based ELF/VLF transmitter, 2) the antenna type and configuration necessary to excite various cavity modes with the radiated ELF/VLF waves, 3) the effects of Landau damping on the ELF/VLFL waves within the cavity, 4) the effectiveness of the radiated ELF/VLF cavity waves in precipitating energetic radiation belt particles, and 5) the optimum spacecraft orbit, antenna configuration, and ELF/VLF transmitter frequency spectmm for precipitating energetic radiation belt particles over a wide range of energies. In addition, a study was carried out concerning the excitation of the magnetospheric cavity by ground-based VLF transmitters.
