Structural and Spatial Effects of the Plasmapause on Magnetospheric Wave Growth

Type: article
Abstract: Singh et al have studied in detail the Whistler mode VLF wave’s intensity enhancement, by assuming change in VII, volume of flux tube, EII change due to a change of position of plasmapause. Enhancing this work, we in place of energy increase, consider the wave growth increase of whistler mode waves. The results are in agreement with reported observations and suggest that plasmapause plays an important role in wave propagation. It is shown that this guidance is possible at both the inner and outer edges of the Plasmapause and that more efficient guide occurs as the Plasmapause gradients become stronger. In the case of strong gradients, waves coming from a wide latitudes range (~80) are focused tightly about the plasmapause field lines, resulting in a wave intensity increase of about 3dB near the magnetic equator plane12.Since plasmapause has inner & outer edges, we can say that it has a width pp) which depends upon Kpmax values, MLT as well as L the McIlwain parameters. pp variation is discussed in next section.
