Acoustic waves focusing with elliptic pillars type metasurface

Résumé

We numerically investigate the focusing properties of an acoustic metasurface consisting of a line of pillars of elliptic shape on a thin plate. We report on the influence of the ellipticity parameter on both monopolar compressional and dipolar bending modes of the pillars. We show that a line of pillars with a gradient in their ellipticity allows to focus the transmitted elastic wave at different targeted points.
