Abstract
The design of a high-performance ultrasound transducer ultimately plays an important role in determining the quality of the image. The simulation based COMSOL Multiphysics (Finite Element Model -FEM) is the most powerful and accurate tool available for this application. The electrical impedance, the transducer center frequency and relative bandwidth of the ultrasound transducer are simulated by using FEM model, and then compared to XTRANS. The key point of the study is that the results between simulation 1D analysis with XTRANS and 2D analysis with FEM model need to be well in agreement to get more reliable, repeatable, and consistent results. Moreover, matching layer thickness of transducer will be set up and changed to survey its influence on the electrical impedance, the center frequency and relative bandwidth of ultrasound transducers.
