Transport in Metamaterails, Light Localisation and transport in dielectric metamaterails
Résumé
Light transport in two-dimensional disordered metamaterials made of high-permittivity rods is studied theoretically. Different regimes of transport are observed and explained in terms of coupled electric and magnetic dipolar resonances. A very general homogenization theory is derived. Light propagation at frequencies close to the magnetic dipole resonance is investigated at the microscopic level and is shown to rely on hybrid, necklace-like, states. The stability of these results versus the permittivity and disorder are investigated.
