| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Brillouin scattering is a nondestructive technique to measure sound velocity propagated in transparent material, using a focused laser beam. This technique enables the evaluation of longitudinal and shear wave velocities in the microscopic region at hypersonic frequencies. However, the measurement accuracy of wave velocities is lower than those of other methods, such as ultrasonic pulse techniques. The accuracy strongly depends on the measurement condition and transparency of the sample, because Brillouin scattering from the thermal phonons is usually weak. In this study, we have tried to overcome this problem making use of the induced longitudinal and shear acoustic phonons excited by ZnO piezoelectric film transducer. To simplify the measurement system, we here report on the use of a coaxial microwave resonator to excite the acoustic phonons without using electrodes. This method enables noncontact generation of electric field in the piezoelectric film. | |
