Multiple scattering of light by disordered assemblies of particles

Our team at the Institute of Light and Matter (iLM) in Lyon (France) is interested in the theoretical and numerical modelling of light scattering and transport in complex media. We study the interaction of electromagnetic waves with structured matter from the nanoscale (e.g., individual wavelength-scale particles) to the mesoscopic scale (e.g., disordered arrangements of hundreds or thousands of particles), to the macroscopic scale (radiative transfer in complex media).

Our research is developed along mainly three axes: (i) Development of new theoretical and numerical tools to model and understand the optical properties of complex media; (ii) Development of new concepts in optics and photonics; (iii) Application of our expertise to solve industrially-relevant problems (integrated photonics, photovoltaics, thermal management, visual appearance design, ...).

We are an integral part of the Modeling of Condensed Matter and Interfaces (MMCI) team, composed of 20-30 people (permanent researchers, post-docs, PhD students, Master interns), with whom we share modelling techniques and computing facilities, alongside great social time.
