Paper Abstract

In this paper, we present an application of the Floquet-Bloch theorem in the context of electrodynamics for vibroacoustique power flow optimization by mean of distributed and shunted piezoelectric patches. The main purpose of this work is first to propose a dedicated numerical approach able to compute the multi-modal wave dispersions curves into the whole first Brillouin zone for periodically distributed 2D shunted piezo-mechanical systems. By using a specific indicator evaluating the evanescent part Bloch's waves, we optimize, in a second time, the piezoelectric shunting electrical impedance for controlling energy diffusion into the proposed semi-active distributed set of cells. A 3D modeling of semi-distributed distribution of the optimal smart metamaterial is used for validating the obtained cell design.
