En el área de las comunicaciones móviles, el álgebra de cuaterniones fue aplicada al estudio de las ecuaciones de Maxwell (descripción de los aspectos de propagación de las ondas electromagnéticas) ya desde los trabajos del mismo Maxwell. Por lo tanto, no resulta extraño que una gran parte de los trabajos científicos modernos utilicen este tipo de técnicas en la resolución del sistema de Maxwel...

We prove that the electromagnetic material parameters are uniquely determined by boundary measurements for the time-harmonic Maxwell equations in certain anisotropic settings. We give a uniqueness result in the inverse problem for Maxwell equations on an admissible Riemannian manifold, and a uniqueness result for Maxwell equations in Euclidean space with admissible matrix coefficients. The proo...

Bankers owed 800 million pounds meet this morning to consider a breathing space for the tottering Maxwell empire, as Ian and Kevin Maxwell struggle to hold their inheritance against potential buyers eyeing assets such as Mirror Group Newspapers.

The aim of this paper is to review and classify the different methods that have been developed to enable stable long time simulations of the VlasovMaxwell equations and the Maxwell equations with sources. These methods can be classified in two types: field correction methods and sources correction methods. The field correction methods introduce new unknowns in the equations, for which additiona...

Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...

The subject matter of this paper concerns the numerical approximation of reduced Vlasov-Maxwell models by semi-Lagrangian schemes. Such reduced systems have been introduced recently in the literature for studying the laser-plasma interaction. We recall the main existence and uniqueness results on these topics, we present the semi-Lagrangian scheme and finally we establish the convergence of thi...
