Granularité laser et interférences de speckles
Boris Chenaud, Pierre Valvin
In this paper we introduce experimentally the phenomenon of speckle and its interferometric applications. With the popularization of CCD sensors and webcams, it is now easy to acqu…

Coherent quasiparticle transport in grain boundary junctions employing high-Tc superconductors
F. Tafuri, A. Tagliacozzo, D. Born +8
Magneto-fluctuations of the normal resistance RN have been reproducibly observed in YBa2Cu3O7-d biepitaxial grain boundary junctions at low temperatures. We attribute them to mesos…

Comment on "Large negative lateral shifts from the Kretschmann-Raether configuration with left-handed materials" Appl. Phys. Lett. 87, 221102, 2005
Antoine Moreau, Didier Felbacq
The negative shifts seen by Wang and Zhu are not due to the excitation of surface plasmons but to leaky modes of the slab propagating backward. Provided the characteristics of the…
