We extend results of [Liu et al. Proc. Roy. Soc. Lond. A 469, 20130240, 2013] on artificial magneto-electric coupling and magnetism in moderate contrast dielectric layered media via high-order homogenization to the three-dimensional setting. For this, we consider asymptotic expansions in the vector Maxwell system. We then illustrate effect of magne...

Love waves are antiplane elastic waves which propagate along the surface of a heterogeneous medium. Under time-harmonic regime, they are governed by a scalar equation of the Helmholtz type. We exploit the invariance of this governing equation under an in-plane arbitrary coordinate transformation to design broadband cloaks for surface defects. In pa...

... In this study we recalled a brief theoretical background and developed a strategy for 3-D elastic cloaking from surface waves, assuming cylindrical symmetry. This idea is an expansion of [4] where only the case of Love waves was considered. We believe that this work can support future extensions, including the realization of a fully feasible and functional elastic cloaking device. ...
