Bloch vector dependence of the plasma frequency in metallic photonic crystals
D. Felbacq, F. Zolla, G. Bouchitte
We show that the plasma frequency in wire photonic crystals depends upon the Bloch vector. An accurate formula is given.

Theory of mesoscopic magnetism in meta-materials
Didier Felbacq, Guy Bouchitte
We provide a rigorous theoretical basis for the artificial magnetic activity of meta-materials near resonances. Our approach is a renormalization-based scheme that authorises a com…

The calibration method for the Mumford-Shah functional and free-discontinuity problems
Giovanni Alberti, Guy Bouchitte', Gianni Dal Maso
In this paper we present a minimality criterion for the Mumford-Shah functional, and more generally for non convex variational integrals on SBV which couple a surface and a bulk te…
