We report a novel approach to control flexural waves in thin plates using metasurfaces
constituted of an array of parallel arranged composite beams with their neutral planes the …

Rotationally resonant metamaterials are leveraged to answer a longstanding question
regarding the existence of transformation-invariant elastic materials and the ad hoc …

In this paper, we explore the concept of structural Luneburg lens (SLL) as a design
framework for performing dynamic structural tailoring to obtain a structural wave cloak and a …

Wave invisibility in confined space has been proved practical significance in mechanical
engineering and military fields. In this work, a flexural wave cloak of a corner-domain target …

The paper initiates a constitutive theory of isotropic linear elastic solids where Cauchy's
stress tensor is not necessarily symmetric thus earning them the attribute “polar”. Mainly …
