Science Daily  December 9, 2021 Electromagnetic ion cyclotron waves (EMIC waves) are an important class of EM wave in Geospace that control variations in the Geospace plasma environment. The EMIC waves are considered to propagate north to south along the geomagnetic field lines. The specific spatial size of the EMIC wave source region and the 3D aspect of how the propagation path is formed from space to ground are yet to be elucidated. An international team of researchers (Japan, USA – University of Colorado, University of Minnesota, Los Alamos National Laboratory, Canada) investigated the growth and propagation of fine-structured EMIC […]
