Research activities
My work is dedicated to the mathematical study of periodic thin layers and periodic gratings. I particularly focus on the following points:
- Construction and analysis of approximate models to simulate periodic thin layers (Asymptotic Analysis, periodic homogenization, matched asymptotic expansions, Maxwell's Equations)
- Simulation of the scattering from periodic gratings using integral equations: development of new methods based on modified periodic green functions that work at wood anomalies.
- Mathematical and numerical investigation of periodic waveguides.
- Numerical simulation.
