Abstract

Various methods and systems are provided for a multi-frequency transducer array. In one example, the transducer array may be fabricated via a wafer scale approach, where a first comb structure, with a first type of element, is formed by dicing a first acoustic stack and a second comb structure, with a second type of element, is formed by dicing a second acoustic stack. Combining the first and second comb structures may form a multi-frequency transducer array.
