  2. 1. Secondary Electromagnetic Radiation Generated by HF Pumping of the Ionosphere

    Author : Lars Norin; Bo Thidé; Savely M. Grach; Bengt Gustafsson; James W. LaBelle; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space physics; ionospheric modification experiments; plasma turbulence; stimulated electromagnetic emission; ionospheric irregularities; radio waves; parametric processes; thermal parametric instability; transient dynamics; wave-wave interactions; Physics; Fysik;

    Abstract : Electromagnetic waves can be used to transmit information over long distances and are therefore often employed for communication purposes. The electromagnetic waves are reflected off material objects on their paths and interact with the medium through which they propagate. READ MORE

  4. 2. Radar Probing of the Sun

    Author : Mykola Khotyaintsev; Bo Thide'; Valentyn Mel'nyk; Christian Hanuise; Uppsala universitet; []
    Keywords : Space and plasma physics; solar radar; active experiments; space physics; solar corona; plasma; Rymd- och plasmafysik;

    Abstract : This thesis is dedicated to the theory of solar radar experiments. The Sun exhibits a variety of interesting and complicated physical phenomena, examined mainly through analysis of its radiation. Active solar probing by radar provides an alternative possibility to study the Sun. READ MORE
