Sub-wavelength focusing of elastic waves in multi-layer structures

In this paper, we develop a rigorous mathematical framework and numerical method for analyzing and computing the subwavelength resonances of multi-layer structures in elastic system, respectively. It is theoretically demonstrated that the number of resonance frequencies increases as the number of resonators increases. There are resonance frequencies for resonators (high contrast domain) within the N-layer structure.
