概要
- 論文の詳細を見る
The systematized computer simulation of the short ultrasonic pulse system is performed using a transmission line model. Optimum condition of the acoustic impedance and thickness of the intermediate layer are considered first. The effects of electrical source impedance for the ultrasonic pulse waveform are also discussed. From the simulation results, the conventional quarter wave acoustic intermediate layer does not always realize optimum pulse performance. The importance of electrical source impedance in pulse performance is also emphasized.
