Abstract: An elastic metamaterial with a lowfrequency passband is proposed by imitating a lattice system with linear onsite potential. It is shown that waves can only propagate in the tunable passband. Then, two kinds of elastic ...

Abstract: As 2D materials with subwavelength thicknesses, elastic metasurfaces show remarkable abilities to manipulate elastic waves at will through artificial boundary conditions. However, current elastic metasurfaces are still far ...
