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,…
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…
Adaptive Tracking Control of Soft Robots using Integrated Sensing Skin and Recurrent Neural Networks
Lasitha Weerakoon, Zepeng Ye, Rahul Subramonian Bama +3
In this paper, we study integrated estimation and control of soft robots. A significant challenge in deploying closed loop controllers is reliable proprioception via integrated sen…
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…
Multi-parameter mechanical and thermal sensing based on multi-mode planar photonic crystals
Yongyao Chen, Haijun Liu, Zhijian Zhang +1
This paper proposes a novel multifunctional sensing platform based on multimode planar photonic crystals (PPCs). We analytically and numerically demonstrate that the reflection spe…
