Abstract(in Japanese) (See Japanese page)
Abstract(in English) Ultrasonic nonlinear phenomina are discussed from Phonon scheme. Using the parametoric decay of phonon, ω-k diagrams are useful for qualitative understanding the phenomena. Cavitation is asymmetric bubble oscillations, i.e., suface waves, which do not easily emitt acoustic energy into water. It was confirmed by experiments. And, we show phase conjugate wave is similar to cavitation from the concept of parametric decay.
