Otsuka; T. Hada; C. H. LinDipolarization of geomagnetic fields had been found to occur at Earth’s tailside during geomagnetic activities associated with decreasing in AL index and substorms [1]. Recently, the dipolarization phenomena were also reported to be observed in the inner magnetosphere [2]. Therefore, it would be essential to investigate properties of waves and particles associated with the dipolarization events. Based on our preliminary analysis from observations of THEMIS mission, both whistler-mode waves and variations in pitch angle distributions of electrons were found at a dipolarization site near the magnetic equator around 10 RE (Earth radii), and changes in energies and pitch angles of electrons according to observed wave parameters were simulated [3]. We found that the observed
