Abstract:

A study of the modifications produced by high power, high frequency HF waves in the F-region of a quiet low solar cycle polar ionosphere is presented. In the polar geometry, maximum Ohmic heating occurs producing significant changes to the zero order electron temperature and density profiles. The temporal and spatial aspects of these changes are calculated and their effects on relevant ionospheric parameters, such as the d.c. conductivity tensor, are found. An interesting finding is the generation of density cavities at the reflection point of the HF waves. A survey of the dependence of the various effects on HF pump parameters is made. Author
