Hydromagnetic Wave Phenomena in the Magnetosphere
Abstract
The propagation characteristics for three model magnetospheres are compared for hydromagnetic waves in the micropulsations frequency range, 0.0001 rad/sec < omega < 1.0 rad/sec. One model is of a plane, layered medium over a plane, conducting earth. A second model is one composed of concentric cylindrical shells of plasma surrounding a conducting, cylindrical earth. In the plane model magnetic field is horizontal, but varies with height. In the second, the stratic magnetic magnetic field is parallel to the cylindrical axis, but again varies with height. The transmission coefficient for the amplitude of the magnetic field of an incident plane hydromagnetic wave is computed as a function of frequency for both models, and the results are compared. The scattering and diffraction effects present in the model with curved surfaces substantially reduce the transmission coefficient at higher frequencies.
