Dynamic Non-Linear Wave Propagation in Ionized Media. 12. Electromagnetic Wave from an Oscillating, Collision Free Magneto-Ionic Medium

摘要

Electromagnetic wave reflection from an oscillating, (e.g., pumped) magneto-ionic medium is treated in detail, also for the slowly inhomogeneous medium, on the basic of the non-linear magneto-ionic theory earlier developed by O.E.H. Rydbeck. The various reflection and refraction laws for the mixed frequency components, and the radiation for the same is discussed in the report. It is also shown that one can make use of non-linear resonance effects to echo sound the ionosphere at mixed frequencies (in the 25 Mc/s range) to obtain the true height of reflection (at the difference frequency) and the electron density gradient. Pulse powers of the order of 5 MW would have to be used for the purpose. (Author)
