Abstract
When designing acoustic metamaterials for complex environments, it is very challenging to derive the acoustic field distribution analytically and obtain the desired devices with the conventional method. Here, we propose to optimize some acoustic devices with inversely design method, which can actively find the optimized structure parameters with prescribed property. This inverse design method avoids the complex analytical calculation and can obtain some performances that are not attainable with the conventional method. This inverse design method takes a significant step towards realizing practical devices and would open up new possibilities for manipulating sound wavefront with optimized performances.
