Modeling of electromagnetic metamaterials
2010 International Conference on Electromagnetics in Advanced Applications, 2010Numerical modeling and experiment have the same importance in revealing the unusual properties of electromagnetic metamaterails. On one hand, the numerical modeling can confirm the experiments on metamaterials; on the other hand, it can explore the properties of metamaterials in extreme conditions which cannot be performed experimentally. In this paper,

Electromagnetic Model of K‐Changes
Journal of Geophysical Research: AtmospheresAbstractK‐changes are observed as step‐like increases in the thundercloud electric fields. The K‐changes occur in the late part of intra‐cloud lightning or during negative cloud‐to‐ground lightning between return strokes. It has been shown that the processes leading to K‐changes initiate in the decayed part of a positive leader channel and propagate ...

Modeling of electromagnetic systems
IEEE Transactions on Magnetics, 1991Modeling techniques are presented for simulation of hybrid (partly electrical, partly magnetic) networks on electrical network simulators. The frequency dependence of the permeability is modeled by a relaxation description, which leads to frequency-independent component values in the network model. The hybrid models can be used for analyses in both the

Electromagnetic Transients and Modelling
2019Transients are the norms and the musts of the energy conversion in power electronics systems. Previous research is focused on the large-timescale electromagnetic transient processes, while neglecting short-timescale switching processes and stray parameters. When failure mechanisms of components and the enhancement of the power-conversion capability are

Publications of the Astronomical Society of the Pacific, 1971
We will briefly review here the general features and predictions of a group of pulsar models which we may class generally as "electromagnetic" models. They are characterized by the supposition that pulsars are rotating neutron stars with strong dipolar magnetic fields, that it is the stress carried by these fields which is responsible for the slowing ...

Advanced Electromagnetic Modeling
2004Abstract : This report presents a fast, high-order hybrid volume/surface integral equation formulation developed under the DARPA VET program for the electromagnetic scattering by composite material targets. The solution is based on a high-order method of moment discretization with quadrature point collocation scheme, shown to be equivalent to the ...

Electromagnetic Theory and Modeling
1998It is well established that electromagnetic theory forms the backbone of electromagnetic interference and compatibility work. A good understanding of electromagnetic theory is highly desirable; however, it does not by itself lead to an understanding of the complexities of the electromagnetic interference phenomenon.

Electromagnetic modelling for EMC
IET 7th International Conference on Computation in Electromagnetics (CEM 2008), 2008Electromagnetic compatibility is a significant application area for electromagnetic modelling techniques. There is strong industrial interest in the development of numerical simulation methods that could allow EMC issues to be investigated in the early stages of design.
