An acoustic impedance of PDMS is of the same order of magnitude as that of water. Therefore, it is considered that the behavior of the pressure waves such as the shock wave and the expansion wave in PDMS is approximately similar to that in water. Practically PDMS is often used in the medical device like ESWL and the acoustic lenses of the ultrasonic diagnosis. Here, two kinds of two-dimensional elliptical reflectors using PDMS was produce. Then, when the shock wave, which was generated in the focal point of the reflector, was reflected in the interface between PDMS and air, it converted to the expansion wave and finally it was focused near the other focul point. In the present study, those phenomena were visualized by Schlieren method using a high-speed camera.英語フィールド
