Electromagnetic resonances in the equatorial ionosphere

A Study on Instabilities and Nonlinear Wave Energy Exchange Process in Terrestrial Ionospheric Plasma

“…Utlaut had studied on enhancement of Langmuir waves in the ionospheric F-layer in 1970 and its discussion was important for future perspective in the collisionless magnetospheric plasma to describe non-linearties of turbulent plasma [57,58]. In the auroral ionosphere, the generation of electric field amplitude modulations of Langmuir wave was observed by Ergun et al [59].…”
