Energy Diffusion of Energetic Electrons by ELF Wave at Low Latitudes

Wave particle interaction between elf waves and cyclotron resonant electrons has been studied & energy diffusion is calculated at low latitude. We consider L-values of low latitudes (1.1, 1.3, and 1.5) and put them into the loss cone to send them into the lower ionosphere. By this way the morphology of the ionosphere changed which helps in elf propagation in earth's ionosphere waveguide. We see that as frequency increases at constant L- values energy diffusion increases .In the same manner we find that L-value is constant and frequency is changed energy diffusion goes on increases. This phenomena helps us in understanding the effect of elf waves on whistler mode propagation and D-E region perturbations and help us in understanding the phenomena of aurorae law farther they are decrease or intense.
