Steering in-plane shear waves with inertial resonators in platonic crystals

Résumé

Numerical simulations shed light on control of shear elastic wave propagation in plates structured with inertial resonators. The structural element is composed of a heavy core connected to the main freestanding plate through tiny ligaments. It is shown that such a configuration exhibits a complete band gap in the low frequency regime. As a byproduct, we further describe the asymmetric twisting vibration of a single scatterer via modal analysis, dispersion, and transmission loss. This might pave the way to functionalities such as focusing and self-collimation in elastic plates.
