Master of Science Theresa Rexerwill on November 24 at 12.15 publically defence her thesis for the PhD degree in Science.
Title of the PhD thesis:
«Radio wave propagation through the ionosphere»
Popular scientific abstract:
As large parts of our modern-day technology and communication are increasingly dependent on electro- magnetic waves and their interaction and propagation in space, the understanding of the interactions between these waves and plasma, the main constituent of the near-Earth space is essential. A specific phenomenon was observed during multiple ionospheric modification experiments, where a radio wave is transmitted into the Earths’ ionosphere and the effects are observed with incoherent scatter radars.
The radio waves, normally reflected here, are observed to propagate through the ionosphere under certain conditions. The waves and the conditions under which they can propagate are identified.
Further, a new calculation method for one of the fundamental ionospheric plasma parameters is presented.
In this thesis, the underlying physics of this phenomenon is explained in detail, and an extensive analysis and discussion of the findings are given by a subject introduction and the accompanying papers.
The thesis is published and available in Munin.
