Spectral extended finite element method for band structure calculations in phononic crystals
Eric B. Chin, Amir Ashkan Mokhtari, Ankit Srivastava +1
In this paper, we compute the band structure of one- and two-dimensional phononic composites using the extended finite element method (X-FEM) on structured higher-order (spectral)…

Scattering under Linear Non Self-Adjoint Operators: Case of in-Plane Elastic Waves
Amir Ashkan Mokhtari, Yan Lu, Qiyuan Zhou +2
In this paper, we consider the problem of the scattering of in-plane waves at an interface between a homogeneous medium and a metamaterial. The relevant eigenmodes in the two regio…
