Abstract
Various methods and systems are provided for a multi-frequency transducer array. In one example, the transducer array is fabricated by forming an interdigitated structure from a first comb structure with a first sub-element and a second comb structure with a second sub-element. The interdigitated structure is coupled to a base package, a matching layer, and a backing layer to form a plurality of multi-frequency transducers.
