Transducer elements have one or more asymmetric features that give rise to multiple natural resonance frequencies. The feature(s) can be discrete (e.g., steps, bars, or gemstone-like facets) or continuous across one or more dimensions of the transducer element (e.g., a triangular prism). A transducer element can be driven at more than one resonance frequency; multiple frequencies will excite more than one feature in parallel, each producing an output emission with a characteristic frequency and phase. An optimal frequency—i.e., one that maximizes the peak acoustic intensity or acoustic power at the target—within a certain frequency range may be determined, and a plurality of asymmetric transducer elements may be driven at a center frequency that coincides with or is close to this optimal frequency.
