Radio Wave Propagation in the Corona and the Interplanetary Medium

  • T. S. Bastian
Conference paper


Radio wave propagation through an inhomogeneous, random plasma produces a variety of observable phenomena — group delay, Faraday rotation, refraction, angular broadening, spectral broadening, and scintillations in phase, amplitude, and frequency. These may be exploited to constrain the mean and fluctuating properties of the medium through a variety of remote sensing techniques. In the case of the solar corona and the solar wind, the mean density, magnetic field, solar wind speed, and the spatial spectrum of the density fluctuations can all be constrained in regions that are inaccessible to in situ measurements.
