Abstract

We study quasistatic cloaking by the mechanism of plasmonic resonance, for systems of coated cylinders. Our focus is on the nature of the resonant cloaking interaction: whether systems of particles can be made to cooperate in cloaking a polarizable particle from an applied uniform field. We show that in fact if the cloaking regions of the systems of particles overlap, then they tend to interact in a fashion detrimental to their cloaking of the polarizable particle. If the cloaking regions touch but do not overlap, then the system of particles can cloak a larger region than each would in isolation. To cite this article: R.C. McPhedran et al., C. R. Physique 10 (2009).

Résumé

Nous analysons le cloaking en régime quasi-statique à travers le mécanisme des résonances plasmoniques, pour des systèmes de cylindres pelliculés. Nous focalisons notre étude sur la nature de l’interaction résonante du cloaking : à savoir si des systèmes de particules peuvent agir de concert pour cloaker une particule polarisable pour un champ extérieur uniforme. Nous montrons qu’en fait si les régions de cloaking du système de particules se chevauchent, alors elles tendent à interagir d’une manière néfaste pour chaque particule. En revanche, si les régions de cloaking se touchent mais ne se chevauchent pas, alors le système de particules peut cloaker un région plus étendue que chaque particule prise isolément. Pour citer cet article : R.C. McPhedran et al., C. R. Physique 10 (2009).
