论文摘要
从理论上讲,我们表明平面波的叠加会导致小(与波长)分散在流体中的颗粒,以组装在二维的两个或三维模式中。我们通过使用超声波在水中使用超声传感器的八角形布置在水中组装碳纳米颗粒的准碘模式来在实验中证明这一理论,我们记录了理论与实验之间的良好一致性。该理论还适用于在其他情况下以线性波(例如光学晶格)移动的其他情况下获得准碘模式。
We theoretically show that a superposition of plane waves causes small (compared to the wavelength) particles dispersed in a fluid to assemble in quasiperiodic two or three dimensional patterns. We experimentally demonstrate this theory by using ultrasound waves to assemble quasiperiodic patterns of carbon nanoparticles in water using an octagonal arrangement of ultrasound transducers, and we document good agreement between theory and experiments. The theory also applies to obtaining quasiperiodic patterns in other situations where particles move with linear waves, such as optical lattices.
