Directional Acoustic Luneburg Lens Waveguide
Liuxian Zhao, Timothy Horiuchi, Miao Yu
This paper investigates the acoustic Luneburg Lens (ALL) as a design framework for guiding acoustic wave propagation. In this study, we propose to develop an acoustic waveguide bas…
Acoustic jet based on acoustic metamaterial
Liuxian Zhao, Timothy Horiuchi, Miao Yu
In this paper, a novel gradient index (GRIN) acoustic metamaterial is proposed based on the concept of optical modified generalized Luneburg lens (MGLL). With the MGLL, double-foci…
Broadband Acoustic Collimation and Focusing using Reduced Aberration Acoustic Luneburg Lens
Liuxian Zhao, Miao Yu
Acoustic Luneburg lens is a symmetric gradient-index lens with a refractive index decreasing radially from the centre to the outer surface. It can be used to manipulate acoustic wa…
Ultrasound Beam Steering with Flattened Acoustic Metamaterial Luneburg Lens
Liuxian Zhao, Eitan Laredo, Olivia Ryan +5
We report ultrasound beam steering based on 2D and 3D flattened acoustic metamaterial Luneburg lenses at 40 kHz. The effective properties of the lenses are obtained by using the qu…
