Beschreibungen/Notizen

• To analyze the ultrasonic field characteristics of high frequency focused transducer in medium, the Gaussian Beam Equivalent Point Source of acoustic field is established by utilizing the advantages of Point Source Superposition Model and Multi-Gaussian Model, and the acoustic field simulation of high frequency focused transducer is conducted. The acoustic field distributions of high frequency focused beam in liquid-solid medium and multilayer medium are studied with this model and calculation and simulation are conducted. Thus, the theoretical basis is provided for the propagation of high frequency ultrasound in medium.
