Topological optimization of periodic materials to enhance anisotropic dispersive effects

Résumé

In the context of waves in periodic media , we propose an iterative algorithm that determines an optimal material distribution to reach target effective dispersive properties. It relies on an homogenized model of this medium, an update procedure based on the topological derivative concept, and on an efficient FFT-accelerated method to solve cell problems.
