Wave propagation through ionospheric plasma in presence of time-varying random irregularities

Summary The dielectric tensor of a time-varying anisotropic electron-plasma has been studied with the consideration of the effect of collision. The tripple splitting of the electromagnetic waves is obtained from the dispersion relation which gives the two usual magnetoionic modes in the limiting case. The randomness of electron number density has been evaluated by the help of field variables and also by the nature of fluctuation of dielectric tensor.
