摘要: AbstractUltrasonic transducer design is focused to maximize performance in specific applications, usually leading complex and expensive construction assembly. With the aim overcome this drawback, a general-purpose immersion ultrasonic for pulsed regime applications has been developed. The of each element described paper, wherein materials geometries part have recommended. A simple theoretical model proposed order predict form received electric signal target transducer. based on assumption that piezoelectric acts as an underdamped oscillator, forced by acoustic field coming from propagation medium. Excellent agreement between experimental measurements analytical achieved. Electrical impedance reveal negligible differences resonance frequency active assembled designe...
