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…
