New ultrasound imaging and therapeutic modalities may require complex transducer designs that are not easily facilitated by conventional design guidelines. This motivates the investigation of numerical optimization methods that can include the effect of structural layers (e.g. bonding and electrodes), electrical loading, and more than one piezoceramic layer in the design and optimization procedure. The aim of his paper is to investigate such numerical design methods and apply this to optimize a transducer by linearizing the phase spectrum.
