Ultrasound Transducer Simulation Page
BioSono provides a cyberspace (www.biosono.com) where researchers, engineers, and students can find useful reference and educational materials, conduct acoustic simulation, post questions on design and development, and get answers. The online KLM based transducer acoustic stack simulation, which is currently free, can help you choose piezoelectric, matching and backing material, and a tuning electrical network. The output from the model includes electrical transmit impedance, acoustic receive impedance, and the impulse or pulse-echo response. The ultrasound beam profile simulation provides the calculated transmitted ultrasound pressure field under certain excitation for a given transducer aperture in a number of different geometrical configurations, including circular elements (flat and concave piston), rectangular elements, linear arrays, convex arrays, and 2D arrays. The simulation is based on Field II, which is a free program that utilizes the spatial impulse response method, and has been validated by many researchers for accuracy. In addition to the web based acoustic simulation, we also provide pulse-echo system, transducers, and customized design and develop services.

Do someone give me some suggestions on how to matching the electric impedance for the whole circuit. I use a 20M function generator, and co-axial cable, and a oscilloscope. the transducer is made by myself, I need the characterize its property.
Many thanks

you need know the real and imaginary part of your transducer impedance at the center frequency.
Then you can use simple serial inductor to cancel the imaginary part by using our Ultrasound Calculator.
A more complicated way is L-shape or T shape matching. It is not widely used.
