| Abstract(in English) | In this study, we calculated sound field converged by acoustical lens constructing from sonic crystal structure. We obtained the characteristics of acoustical lens using Finite Difference Time Domain method. By comparing characteristics of acoustical lens between simulation and experiment, we measured convergence field by acoustical lens in experiment using simplify model of acoustical lens with stainless steels. As a result, focal distance and beam width almost same between simulation result and experiment result. |
