Svalgaard, and independently Mansurov, discovered a correspondence between the geomagnetic variations at the geomagnetic poles and the sector polarity of the interplanetary magnetic field (IMF). Heppner noted an asymmetry in the magnetospheric electric convection field observed within the polar caps at ionospheric altitudes which is also related to the sector polarity of the IMF. It is shown th...

The Maxwell equations describe the interaction of electric and magnetic fields. Important applications are electric machines such as transformers or motors, or electromagnetic waves radiated from antennas or transmitted in optical fibres. To compute the solutions of real life problems on complicated geometries, numerical methods are required. In this lecture we formulate the Maxwell equations, ...

In this article, we present a computational framework for solving problems arising in electromagnetism. The framework is derived from a modern geometrical approach and is based on differential forms (or p-forms). These geometrical entities provide a natural framework for modeling of physical quantities such as electric potentials, electric and magnetic fields, electric and magnetic fluxes, etc....

A theoretical study of the mobility of n-doped III-Nitrides in wurtzite phase is reported. We have determined the nonequilibrium thermodynamic state of the bulk n-InN, n-GaN, and n-AlN systems driven far away from equilibrium by a strong electric field in the steady state, which follows after a very fast transient. For this we solve the set of coupled nonlinear integro-differential equations of...

Random walk theory is applied to the motion of electrons in the early stage of breakdown of helium in an electric field. Details of inelastic and elastic interactions are based on integral and differential cross section data. The concept of mean free time is extended to include the effect of acceleration between collisions due to the electric field. The relaxation of electron energy distributio...

Whole body electrocution can cause many and quite different changes depending on a number of factors, notably the level and type of current, the carrier of electricity, the chain of external causes and the person affected (1). The effects of electric current on various tissues and on body metabolism have been studied extensively (2, 3, 4, 5). The effects of electric field on different cell memb...

It is hypothesized that high frequency components of nanosecond pulsed electric fields (nsPEFs), determined by transient pulse features, are important for maximizing electric field interactions with intracellular structures. For monopolar square wave pulses, these transient features are determined by the rapid rise and fall of the pulsed electric fields. To determine effects on mitochondria mem...

Irreversible electroporation (IRE) ablation uses brief electric pulses to kill a volume of tissue without damaging the structures contraindicated for surgical resection or thermal ablation, including blood vessels and ureters. IRE offers a targeted nephron-sparing approach for treating kidney tumors, but the relevant organ-specific electrical properties and cellular susceptibility to IRE electr...

The current rectification displayed by solid-state p-n semiconductor diodes relies on the abundance of electrons and holes near the interface between the p-n junction. In analogy to this electronic device, we propose here the construction of a purely ionic liquid-state electric rectifying heterojunction displaying an excess of monovalent cations and anions near the interface between two immisci...
