Abstract
Various methods and systems are provided for a multi-frequency transducer array. In one example, ground recovery in the transducer array is enabled by configuring an acoustic stack of the transducer array with an interdigitated structure, a top layer coupled to a front side of the interdigitated structure, and a bottom layer coupled to a back side of the interdigitated structure, where the top layer and the bottom is electrically continuous with the interdigitated structure.
