Propagation through the ionosphere the ultraviolet ranges. In fact, absorption sets the decisive limits to groundbased optical astronomy. The situation is quite different with radio waves. While strong absorption occurs only in certain frequency ranges and at certain hours (e.g. for LF and MF waves during daylight hours), the most i

Collisional attenuationsion frequency”, ., which was not physically specified. In Equation (4.5) we have merely replaced the average particle acceleration by a formal tenir . instead of .. The conditions under which collisions influence the propagation of radio waves shall now be considered in more detail..

Kinetic theory of a Lorentz plasmaopagation has not been admitted in Chapters 1 to 12. This was justified by the fact that the individual contributions to the current density should compensate each other due to the isotropy of the thermal motions. Almost all phenomena observed with ground-based ionospheric sounding can indeed be exp

The Boltzmann equation of a compressible plasma a sound basis for discussing a large variety of phenomena that cannot be understood in the framework of the “cold theory” considered in Part A. Some simplifications are, fortunately, permitted in many applications.
