Local metamaterials and transition layers
Kimya Yadollahpour, Hossein Khodavirdi, Ankit Srivastava
In this paper, we elucidate the concept of local acoustic metamaterials. These are composites which exhibit equi-frequency contours (EFC) which correspond to those expected of homo…

The Atomistic Green's Function method for acoustic and elastic wave-scattering problems
Hossein Khodavirdi, Zhun-Yong Ong, Ankit Srivastava
In this paper, we present a powerful method (Atomistic Green's Function, AGF) for calculating the effective Hamiltonian of acoustic and elastic wave-scatterers. The ability to calc…
