Elastodynamic transformation cloaking for non-centrosymmetric gradient solids

In this paper we investigate the possibility of elastodynamic transformation cloaking in bodies made non-centrosymmetric gradient solids. The goal is to hide a hole from elastic disturbances sense that mechanical response homogeneous and isotropic body with covered by cloak would be identical corresponding outside cloak. It known case centrosymmetric solids balance angular momentum obstruction cloaking. We will show for as well.
