MWSW02 - Theory of wave scattering in complex and random media

Disordered ensembles of resonant particles deposited onto or incorporated into layered media are becoming widespread in optics and photonics. Predicting the optical response of such complex structures can however be difficult, due to the possibly high-order multipolar resonances of the particles and the intricate electromagnetic interaction between particles in a layered environment. In this communication, I will present the outcomes of recent efforts to model theoretically the specular and diffuse components of the average intensity scattered by disordered monolayers of resonant particles on layered substrates. Theoretical predictions will be compared with full-wave T-matrix simulations on open, finite-size systems and periodic supercells using a numerical code developed at the Institut d’Optique Graduate School. This will help us defining the main challenges lying ahead and some promising applications in optics and photonics. Co-authors: Louis Bellando, Armel Pitelet and Philippe Lalanne
