This paper proposes a mathematical model of electric fields caused by high voltage conductors of electric power transmission systems by using a set of second-order partial differential equations. This study has considered the effect of conductor phase-sequence orientation on electric fields emitted around a doublecircuit, extra high-voltage, power transmission line. Six typical-used phase-seque...

For Electric Vehicles (EVs), Weight and losses reduction are important factors not only in reducing the energy consumption and cost but also in increasing autonomy. This paper describes the application of an evolutionary algorithm for multiobjective optimization in the traction chain (TC) of pure EV. In this study, the optimisation algorithm is based on the Strength Pareto Evolutionary Algorith...

Anharmonic interactions in lattices may sustain robust oscillatory modes and (nonlinear) waves including solitons. This is illustrated here by using an exponentially repulsive interaction introduced by Toda. To cope with friction and dissipation -always present in real systemsand hence to make robust, e.g., solitons, following Lord Rayleigh, an appropriate input-output energy balance is added t...

We study an electrolyte confined in a slab of width W composed of two grounded metallic parallel electrodes. We develop a description of this system in a low coupling regime beyond the mean-field (Poisson-Boltzmann) approximation. There are two ways to model the metallic boundaries: as ideal conductors in which the electric potential is zero, and it does not fluctuate, or as good conductors in ...

Abstmct-An annular aperture antenna mounted on an infinite ground plane and containing a hemispherical center conductor extension above the ground plane is investigated. A Green’s function for the region above the ground plane is derived so as to be compatible with numerical solution techniques. A magnetic field integral equation is obtained in terms of the unknown tangential aperture electric ...

In this paper, the region of interest consists of a perfect conductor, coated with the two layer dielectrics under the air. The completed analytical formulas have been derived for the electromagnetic field due to a vertical electric dipole in the four-layered region when both the source point and observation point are located in the upper dielectric layer. Similar to the three-layered case, the...

The time-harmonic eddy current problem with either voltage or current intensity excitation is considered. We propose and analyze a new finite element approximation of the problem, based on a weak formulation where the main unknowns are the electric field in the conductor, a scalar magnetic potential in the insulator and, for the voltage excitation problem, the current intensity. The finite elem...
