Abstract: We study the propagation of Lamb waves in a one-dimensional tunable phononic metastrip composed of a periodic sequence of hollow pillars that can be selectively filled with water. Band structures and transmission properties are computed… read more here.

Abstract: Current strategies for designing tunable locally resonant metamaterials are based on tuning the stiffness of the resonator; however, this approach presents a major shortcoming as the effective mass density is constant at high frequency. Here,… read more here.
