Total-internal-reflection elastic metasurfaces: design and application to structural vibration isolation
Hongfei Zhu, Timothy F. Walsh, Fabio Semperlotti
This letter presents the concept of Total Internal Reflection metasurface (TIR-MS) which supports the realization of structure-embedded subwavelength acoustic shields for elastic w…

Double-zero-index structural waveguides
Hongfei Zhu, Fabio Semperlotti
We report on the theoretical and experimental realization of a double-zero-index elastic waveguide and on the corresponding acoustic cloacking and supercoupling effects. The propos…
