声波远场超分辨放大透镜设计
esign acoustic magnifying lens for far-field super-resolution imaging
论文基于各向异性等效质量和共振隧穿效应,研究了近场凋落波的远程传输及其传播模式的调控机制,进而用于实现声波远场高分辨成像。基于上述原理设计出一种平面型远场放大透镜,通过数值模拟证明该透镜具有远场高分辨放大成像功能。
he paper studies the transferring and conversion mechanisms for near-field evanescent waves based on the concept of anisotropic mass and resonant tunneling. The concepts can be used to design an acoustic planar magnifying lens. Numerical simulations are conducted to verify the capability of the lens for far-field super-resolution imaging.
