Abstract

There is a clear need to power electronic components wirelessly. Various applications cannot be powered by wired or electromagnetic means. Acoustic energy transfer (AET) is an effective method in powering devices sealed or shielded by walls, and such applications are termed though-wall AET systems. These systems are constructed of a transmitter and a receiver that are bonded on opposite sides of the wall. Through-wall AET systems are typically modeled as three-layer systems. This method does not account for the additional layers created by the bonding agents that connect the transducers to the wall. Additionally, modeling of such systems assumes motion solely in the thickness direction. This assumption implies that the system undergoes “piston-like” deformation. This work addresses the need to computationally investigate through-wall AET systems and address the consequences of the aforementioned assumptions.
