提出了一种基于变换声学的亚波长分辨成像声学材料透镜设计方法。所提出的声学放大器在宽带上产生高分辨率。从5650 Hz到6350 Hz的范围内数值模拟了高分辨率成像特性的影响。这是一个重要的属性,可以在许多潜在的应用,包括高度亚波长医疗诊断和检测的实施中利用。
We propose a new approach to design acoustic metematerials lens for subwavelength resolution imaging based on transformation acoustics. The proposed acoustic magnifier creates high resolution over broadband. The high-resolution imaging property effect is demonstrated numerically from 5650 Hz to 6350 Hz. This is an important property that can be leveraged in many potential applications, including the implementation of highly sub-wavelength medical diagnose and detection.
