CMA-ES based topology optimization for acoustic cloak

CMA-ES based topology optimization for acoustic cloak

This paper presents a topology optimization based on a covariance matrix adaptation evolution strategy (CMA-ES) for acoustic cloaks rendering a scattering object acoustically invisible. The cloaks are designed by minimizing the scattering of acoustic waves around the object and the objective functio...
