Optimization of Graded Metamaterials for Control of Energy Transmission Using a Genetic Algorithm
Joshua Morris, Weidi Wang, Thomas Plaisted +2
Optimization of functionally graded metamaterial arrays with a high dimensional and continuous geometric design space is cumbersome and could be accelerated via machine learning to…
Reduced Order Modeling of Dynamic Mechanical Metamaterials for Analysis of Infinite and Finite Systems
Weidi Wang, Alireza Amirkhizi
Dynamic mechanical metamaterials (MMs) are artificial media composed of periodic micro-structures, designed to manipulate wave propagation. Modeling and designing these materials c…
Angle-dependent Phononic Dynamics for Deep Learning and Source Localization
Weidi Wang, Amir Ashkan Mokhtari, Ankit Srivastava +1
In this work, a parameterized eigenvalue problem is analyzed for a phononic array in a 2D stress wave scattering setup, and a corresponding sensing application of this system is pr…
Learning Order Parameters from Videos of Dynamical Phases for Skyrmions with Neural Networks
Weidi Wang, Zeyuan Wang, Yinghui Zhang +2
The ability to recognize dynamical phenomena (e.g., dynamical phases) and dynamical processes in physical events from videos, then to abstract physical concepts and reveal physical…
Exceptional points and scattering of discrete mechanical metamaterials
Weidi Wang, Alireza V. Amirkhizi
Exceptional points (EPs) are complex singularities of parametric linear operators where two or more eigenvalues and eigenvectors coalesce. EPs are attracting increasing interest in…
Reduced order derivation of the two-dimensional band structure of a mixed-mode resonator array
Alireza V. Amirkhizi, Weidi Wang
In this paper, the 2D band structure of a mixed-mode metamaterial resonator array for in-plane waves is investigated. The band structure in the interior and on the boundary of the…
