Large-Angle Bending Transport of Microparticles by Acoustic Half-Bessel Beams
Yixiang Li, Chunyin Qiu, Shengjun Xu +2
Conventional microparticle transports by light or sound are realized along a straight line. Recently, this limit has been overcome in optics as the growing up of the self-accelerat…

Focusing and directional beaming effects of airborne sound through a planar lens with zigzag slits
Kun Tang, Chunyin Qiu, Jiuyang Lu +2
Based on the Huygens-Fresnel principle we design a planar lens to efficiently realize the interconversion of the point-like source and Gaussian beam in the air ambience. The lens i…

Deep Subwavelength Electromagnetic Transparency through Dual Metallic Gratings with Ultranarrow Slits
Chunyin Qiu, Sucheng Li, Ruirui Chen +3
In this Letter, we study the transmission response of microwaves through two identical metallic plates machined with ultranarrow slit arrays. The measured and calculated transmissi…
