Antiplane elastic wave cloaking using metamaterials, homogenization and hyperelasticity
WJ Parnell, T Shearer - Wave Motion, 2013 - Elsevier
We consider the problem of how to cloak objects from antiplane elastic waves using two
alternative techniques. The first is the use of a layered metamaterial in the spirit of the work …
