Non-reciprocal sound propagation in space-time modulated media
Junfei Li, Chen Shen, Yangbo Xie +1
Realization of non-reciprocal devices, such as isolators and circulators, is of fundamental importance in microwave and photonic communication systems. This can be achieved by brea…
GRIPP: an automated computer-aided design tool for generating 3D printable gradient index acoustic devices
Yangbo Xie, Steven A. Cummer
Gradient index (GRIN) acoustic devices have spatially inhomogeneous refractive index profile and allow flexible control of the propagation of acoustic waves. Previous GRIN acoustic…
Compact Acoustic Retroreflector Based on A Mirrored Luneburg Lens
Yangyang Fu, Junfei Li, Yangbo Xie +4
We propose and demonstrate a compact acoustic retroreflector that reroutes probing signals back towards the source with minimal scattering. Gradient refractive index (GRIN) acousti…
Acoustic Metacages for Omnidirectional Sound Shielding
Chen Shen, Yangbo Xie, Junfei Li +2
Conventional sound shielding structures typically prevent fluid transport between the exterior and interior. A design of a two-dimensional acoustic metacage with subwavelength thic…
Acoustic Holographic Rendering with Two-dimensional Metamaterial-based Passive Phased Array
Yangbo Xie, Chen Shen, Wenqi Wang +5
Acoustic holographic rendering in complete analogy with optical holography are useful for various applications, ranging from multi-focal lensing, multiplexed sensing and synthesizi…
Broad-band acoustic hyperbolic metamaterial
Chen Shen, Yangbo Xie, Ni Sui +3
Acoustic metamaterials (AMMs) are engineered materials, made from subwavelength structures, that exhibit useful or unusual constitutive properties. There has been intense research…
