Abstract
Linearly polarized electromagnetic waves traveling through cold magnetized plasma experience Faraday rotation. The Appleton Hartree dispersion equation relates the phase shift on any electromagnetic ray to the magnetic field B, ion-electron density Ne and the angle the ray makes with the instantaneous magnetic field. This work uses the dispersion relation to calculate small time scale magnetic perturbations in the ionosphere due to electrojet current systems. The ionosphere is modeled as a collision free cold plasma with synthesized small scale magnetic perturbations. The work presented here simulates test cases, where the satellites transmits three amateur satellite radio band frequencies (7M Hz, 14M Hz, and 144M Hz) at fixed intervals. The ionosphere model is then used to evaluate the phase shift on the transmitted signals. The phase shift of the signal is used in conjunction with the Appleton Hartree dispersion relation to determine the resultant B field in the ionosphere.
