Transmission Line Model for Driving Plasma Convection in the Inner Magnetosphere

摘要: The plasma convection in the inner magnetosphere reacts quickly after a growth of polar cap potential, as revealed by quick onset development partial ring current demonstrated Hashimoto et al. [2002]. In order to explain response magnetosphere, we apply Earth-ionosphere waveguide (transmission line) model developed Kikuchi and Araki [ 979b]. this paper, examine how TMO mode is excited electric potential transported along with field-aligned currents, show that transmitted horizontally at speed light waveguide. We then evaluate attenuation calculating Poynting flux upward from into conducting ionosphere. A fraction further when Alfven conductance not very small compared ionospheric conductance. transportation causes loss transmitting energy, resulting mode, but it substantial geometrical due finite size field. stress field associated mapped which drives magnetosphere. note ionosphere generator constitutes transmission line for electromagnetic energy be
