  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 new functionalities such as
focusing and self-collimation in elastic plates.
