论文摘要
现在，几乎每个物理领域都已经确定了掩盖效果。在所有情况下，底物雕刻的过度材料使得不可能重塑隐藏的体积。在流体中，我们认识到D'Alembert的悖论本身描述了一种流体动力掩盖机制，因此我们提出并在实验上表征了一个框架，以在可重塑的流体体积中同时堵塞流动和运输。进一步研究了微流体斗篷作为开放空间扩散过滤器（O滤波器）的性质。它们揭示了与微流体学中经典的H滤波器的强烈拓扑类比。
Cloaking effects have now been identified in almost every field of physics. In all cases, substrate-carved metamaterials make the reshaping of the concealed volume impossible. In fluids, recognizing that d'Alembert's paradox describes in itself a hydrodynamic cloaking mechanism, we propose and characterize experimentally a framework to cloak both flow and transport simultaneously within a reshapable fluid volume. The properties of microfluidic cloaks as open-space diffusion filters (O-Filters) are further investigated. They reveal a strong topological analogy with classical H-Filters in microfluidics.
