Magnon propagation in a nanometric magnetic cluster chain : effects of additional clusters near the chain

Housni Al-Wahsh, L. Dobrzynski, Bahram Djafari-Rouhani, Gregorio Hernandez-Cocoletzi, Abdellatif Akjouj

A fundamental understanding of nanoscaled materials has become an important challenge for any technical applications. For magnetic nanoparticles, the investigations are in particular stimulated by the magnetic storage devices. In this paper we present a theory of the magnon propagation in a…

Electromagnetic wave propagation in quasi-one-dimensional comb-like structures made up of dissipative negative-phase-velocity materials

Gregorio Hernandez-Cocoletzi, L. Dobrzynski, Bahram Djafari-Rouhani, Housni Al-Wahsh, Driss Bria

We study the propagation of electromagnetic waves in infinite lines with grafted finite lines in a frequency regime, where the grafted lines have negative phase velocity. The physical properties of such a structure with negative phase velocity materials have not been investigated before, to the…

On the use of a performance indicator for optimal pilot positioning in multicarrier systems

David Buèche, Patrick Corlay, Marc G. Gazalet, François-Xavier Coudoux, Marc Slachciak

We have recently proposed a simple performance indicator for discrete multitone systems, which accounts for the channel estimation error, the emitted power and the noise level. It shows a much better correlation with the bit error rate (BER) than the more classical mean square error (MSE) while…
