Analysis of subwavelength resonances in high contrast elastic media by a variational method
Bochao Chen, Yixian Gao, Peijun Li +1
In this paper, we present a mathematical study of wave scattering by a hard elastic obstacle embedded in a soft elastic body in three dimensions. Our contributions are threefold. F…

Modal approximation for time-domain elastic scattering from metamaterial quasiparticles
Bochao Chen, Yixian Gao, Hongyu Liu
This paper aims at quantitatively understanding the elastic wave scattering due to negative metamaterial structures under wide-band signals in the time domain. Specifically, we est…
