Acoustic Metamaterial Beam Splitter
Liuxian Zhao
This paper proposes an acoustic beam splitter based on acoustic Luneburg lens. A two-dimensional acoustic Luneburg lens with gradient refractive index is achieved to provide a prac…
Structural Lens Based on Variable Thickness Structures
Liuxian Zhao, Chuanxing Bi, Miao Yu
In this article, we report a lens design based on a concentric circular structure with continuous changing of thickness defined in a thin plate structure for focusing a plane wave…
Acoustic Lenses Design based on the Rays Inserting Method
Liuxian Zhao, Chuanxing Bi, Miao Yu
The ability to control and manipulate elastic waves is important for applications such as structural health monitoring, signal processing, and vibration isolations. In this paper,…
Ultralong Wave Focusing via Generalized Luneburg Lens
Liuxian Zhao, Miao Yu
In this paper, a novel gradient index (GRIN) structural lens based on the concept of generalized Luneburg lens (GLL) is proposed. This lens allows for the realization of double foc…
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…
Realization of Flattened Structural Luneburg Lens Based on Quasi-Conformal Transformation
Liuxian Zhao, Miao Yu
Conventional structural Luneburg lens is a symmetric circular gradient-index lens with refractive indices decreasing from the centre along the radial direction. In this paper, a fl…
Bi-functional Structural Luneburg Lens for Broadband Structural Wave Cloaking and Waveguide
Liuxian Zhao, Miao Yu
In this paper, we explore the concept of structural Luneburg Lens (SLL) as a design framework for performing dynamic structural tailoring to obtain a structural wave cloak and a st…
Multi-Functional Variable Thickness Structure for Broadband and Omnidirectional Focusing and Collimation
Liuxian Zhao, Changquan Lai, Miao Yu
Luneburg lens is a symmetric gradient-index lens with a refractive index that increases from the outer surface to the center in a radial manner. It has the ability to focus and col…
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…
