We study the scattering by rough surfaces, rough inhomogeneous films and we propose new formulations for the effective permittivity of random media.
We develop narrow-band filters and directionnal sources with dielectric waveguide gratings. We modify the dispersion relation of guided waves with periodic structurations
We develop an optical diffraction tomograph which presents a better power of resolution than classical microscopes.
We propose a volume integral method for simulating the field diffracted by a 3D object in a complex environment (multilayer,grating).
