Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	We report measurements of the temperature dependence of the surface impedance in superconducting BaFe1.93Ni0.07As2 crystals using the radiofrequency reflection technique in the 5<T<30K temperature range. An LC resonant circuit with a phase sensitive detection was used at 92MHz. A measurement…

Scattering forces on magneto-dielectric particles and the electromagnetic momentum density
Marques, Manuel I.; Universidad Autonoma de Madrid - Saenz, Juan J.; Universidad Autonoma de Madrid

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	In this paper we analyze the non-conservative forces on magneto-dielectric particles in special configurations where the scattering force is not proportional to the average value of the Poynting vector. Based on these results, we revisit the concept of electromagnetic momentum…

The premetric approach to electromagnetism in the 'waves are not vectors' debate
Bossavit, Alain; LGEP, CNRS, University Paris Sud

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…

Difficulties in teaching electromagnetism: an eight year experience at Pierre and Marie Curie University
Roussel, Hélène; UPMC, Univ. Paris 6 - Hélier, Marc; UPMC, Univ. Paris 6

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…

Frequency Dependent Model of Leakage Inductance for Magnetic Components
Wilson, Peter R; School of Electronics and Computer Science University of Southampton Southampton SO17 1BJ United Kingdom

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…

Curvilinear vector finite difference approach to the computation of waveguide modes
Fanti, Alessandro; University of cagliari - Mazzarella, Giuseppe; University of cagliari - Montisci, Giorgio; University of cagliari

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…

Polarizability Matrix Extraction of a Bianisotropic Metamaterial from the Scattering Parameters of Normally Incident Plane Waves
Karamanos, Theodosios D.; Aristotle University of Thessaloniki - Dimitriadis, Alexandros I.; Aristotle University of Thessaloniki - Nikolaos V., Kantartzis; Aristotle University of Thessaloniki

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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,…

Surface Plasmon - Guided Mode strong coupling
Castanié, Aurore; University of Montpellier 2 - Felbacq, Didier; University of Montpellier 2 - Guizal, Brahim; University of Montpellier 2

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…

On the dynamics of cutting arc plasmas: the role of the power supply ripple
Prevosto, Leandro; Grupo de Descargas Eléctricas, Departamento Ingeniería Electromecánica, Facultad Regional Venado Tuerto (UTN), Laprida 651 (2600) Venado Tuerto (Santa Fe), Argentina

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…

Reducing radar cross section by investigation electromagnetic materials
Komeylian, Somayeh; Islamic Azad University South - Hojjat-Kashani, Farrokh; University of Science and Technology

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Peer-reviewed Article
Enlaces:	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…
