| Research Abstract |
The final goal in this study, we develop the acoustic imaging system in Ocean using flexible acoustic lens constructed with phononic crystal structure. For the obtaining of basic properties of the planate acoustic lens, we produced the prototype of the planate lens constructed by stainless steel. In this study, we measured convergence field by planate acoustic lens in water tank. In addition, we simulated convergence field by planate acoustic lens using finite difference time domain(FDTD) method. As a result, we confirmed the lens effect of designed planate lens. Measurement result of focal distance and-3 dB beam width was almost good agreement with simulation result using FDTD method.
