This paper demonstrates the realization of the electromagnetically induced transparency (EIT)-like transmission in a metamaterial plasma waveguide with double side defects based on transmission lines. The waveguide with a single side defect works as a plasma resonator and the resonance…

This paper deals with the High-Order Method of Moments (HO-MoM) combined with Non-Uniform Rational Basis Splines (NURBS) segments to evaluate the scattering by a 2D cylinder. The authors mainly focus upon the influence of the different parameters (polynomial basis, order,…

A plea for the introduction, in advanced electromagnetics courses, of some basic differential geometric notions:  covectors,  differential forms, Hodge operators.  The main advantages of this evolution should be felt in computational electromagnetism.  It may also shed some new light on the…

We will begin by outlining the details of how electromagnetics are taught in the  electrical engineering program offered at Pierre and Marie Curie University (a French example) from the undergraduate to the Masters degree levels.  We will also discuss how…

Theoretical methods for the calculation of winding losses with respect to frequency have been well documented, but the variation in leakage inductance of magnetic components due to frequency has been less well addressed. In this paper Dowell’s well-known theoretical approach…

We describe here a Vector Finite Difference approach to the evaluation of waveguide eigenvalues and modes for rectangular, circular and elliptical waveguides. The FD is applied using a 2D cartesian, polar and elliptical grid in the waveguide section. A suitable…

In this paper, a polarizability matrix retrieval method for bianisotropic metamaterials is presented. Assuming that scatterers can be modeled by electric and magnetic pointdipoles located at their centers, the induced dipole moments are analytically related to the normally incident fields,…

It is shown that it is possible to realize strong coupling between a surface plasmon and a guided mode in a layered structure. The dispersion relation of such a structure is obtained through the S-matrix algorithm combined with the Cauchy integral technique that allows…

The power sources used in cutting arc torches are usually poorly stabilized and have a large ripple factor. The strong oscillatory components in the voltage and arc current produce in turn, large fluctuations in the plasma quantities. Experimental observations on…

Decreasing the Radar Cross Section (RCS) is investigated in electromagnetic materials, i.e. double-positive (DPS) , double-negative (DNG) , epsilon-negative (ENG) and mu-negative (MNG) materials. The interesting properties of these materials lead to a great flexibility in manufacturing structures with unusual…
