Modulation of Observed Thomson Scattering Spectra in a Plasma Density Irregularity

By Valery A. Puchkov
Progress In Electromagnetics Research Letters, Vol. 72, 113-118, 2018


Thomson scattering of an electromagnetic wave in a plasma density irregularity is considered. A new effect is found that the scattered waves generation and superposition near the electron density extremum may result in a substantial modulation of the scattered signal frequency spectrum. Due to this effect, the observable spectrum shape will be substantially different from that for the electron density fluctuations. This fact should be taken into account when interpreting Thomson scattering experiments.
