Ionospheric disturbance magnetic field continuation from the ground to the ionosphere using spherical elementary current systems
A new technique for continuation of the ground magnetic field caused by ionospheric currents to the ionosphere in spherical geometry is presented that makes use of elementary ionospheric current systems, which were introduced by Amm (1997) in extension of an earlier work by Fukushima (1976). The measured ground magnetic disturbance is expanded in terms of the ground magnetic effect of a spatial...
متن کاملResults from Automated Ionospheric Data Analysis for Ground-Based Augmentation Systems (GBAS)
Extremely large ionospheric spatial gradients could cause potential integrity threats to Ground-Based Augmentation System (GBAS) users. The importance of understanding ionosphere behavior is not limited to cases of extreme ionospheric events. Broader knowledge of both nominal and anomalous ionospheric behavior would help improve the design and operation of GBAS. We developed an automated tool f...
متن کاملCalculating the Field Emission Current from a Carbon Nanotube
The purpose of this work is to present elements of a design tool for field emission displays using carbon nanotubes as emitters. We use a continuum model to describe the carbon nanotubes and we use a locally one-dimensional approximation to calculate the emission current. We investigate the emission current to voltage characteristic, screening effects and the lateral spread of the emission curr...
متن کاملCurrent-carrying ground states in mesoscopic and macroscopic systems.
I extend a theorem of Bloch, which concerns the net orbital current carried by an interacting electron system in equilibrium, to include mesoscopic effects. I obtain a rigorous upper bound to the allowed ground-state current in a ring or disk, for an interacting electron system in the presence of static but otherwise arbitrary electric and magnetic fields. I also investigate the effects of spin...
متن کاملThe effects of dynamic ionospheric outflow on the ring current
[1] The importance of ionospheric O on the development of the storm time ring current is recognized but not well understood. The addition of this outflow in global MHD models has the potential to change the magnetic field configuration, particle densities and temperatures, and the convection electric field. This makes including heavy ion outflow in ring current simulations difficult, as this ad...
