Effect of angle of propagation and spatial extent of a gravity wave on Faraday rotation
Abstract
The influence of gravity waves on ionospheric perturbation is considered with particular attention given to the effect on Faraday rotation, the angle of gravity propagation, and the implications of gravity waves with less than infinite spatial extent. The perturbation in electron density at several altitudes is multiplied by the corresponding magnetic field factor to derive the contribution to perturbation in the rotation of the plane of polarization. The fractional perturbation in Faraday rotation at any altitude is found to increase with the angle of propagation until a critical value is met. Variables such as period, velocity, azimuth of propagation and altitude determine the critical propagation angle; wind also affects the angle to a degree. The procedure is effective for calculating the spatial position of the gravity waves and their effects on both Faraday rotation and TEC.
