|Abstract:||The whistler mode waves propagating through the ionosphere suffer major part of dispersion. The detailed analysis of whistler sonogram is likely to predict the role of ionospheric field and plasma parameters. With this end in view the role of finite parallel electric field has been accounted and the appropriate dispersion equation for whistler mode wave propagation has been derived. Using this dispersion equation the refractive index surfaces have been constructed. The variation of wave normal direction for varying angle of ray propagation has been computed. The parallel and antiparallel electric fields change the phase velocity of whistler mode waves and focus or defocus the waves along the static magnetic field lines. In the presence of parallel or anti parallel electric field the propagating whistler mode wave becomes unstable and is subjected to a finite growth or decay whose magnitude depends on the electric field and the plasma parameters.|
