Rigorous asymptotic study of the screened electrostatic potential in a thin dielectric slab
Didier Felbacq, Emmanuel Rousseau
The screened Coulomb potential plays a crucial role in the binding energies of excitons in a thin dielectric slab. The asymptotic behavior of this potential is studied when the thi…
Weak and strong coupling of a quantum emitter with a meta-surface
Didier Felbacq
Meta--surfaces are the bidimensional analogue of metamaterials. They are made on resonant elements periodically disposed on a surface. They have the ability of controlling the pola…
Collective resonant modes of a meta-surface
Didier Felbacq, Emmanuel Rousseau, Emmanuel Kling
A periodic layer of resonant scatterers is considered in the dipolar approximation. An asymptotic expression for the field diffracted is given in terms of an impedance operator. It…
Homogenizing metamaterials, three times
Didier Felbacq
The homogenization of a metamaterial made of a collection of scatterers periodically disposed is studied from three different points of view. Specifically tools for multiple scatte…
A quantum way for metamaterials
Didier Felbacq
A new future for metamaterials is suggested, involving the insertion of quantum degrees of freedom, under the guise of quantum dots or cold atoms, in an photonic matrix. It is argu…
Mesoscopic magnetism in dielectric photonic crystal meta materials: topology and inhomogeneous broadening
Niels Asger Mortensen, Sanshui Xiao, Didier Felbacq
We consider meta materials made from a two-dimensional dielectric rod-type photonic crystal. The magnetic response is studied within the recently developed homogenization theory an…
