摘要
基于声子晶体的负折射效应以及多重散射理论,研究了实现点声源完美成像的方法及过程,并利用有限元法在COMSOL软件中给吸收体设定与激光照射一样的激励源,进行了模拟探究,得到完美成像的仿真结果.
Based on the negative refraction effect of phononic crystal,and multiple scattering theory studies the method and process relative to the imaging implementation of point source.And then the author,by making the finite element method,makes an experiment in the COMSOL software setting the same excitation source as laser,Finally,the author gets perfect imaging simulation results.All the research makes great progress in development and application of scientific instruments.
