Elastic wave control in reticulated plates using Schwarz primitive cells
Aida Hejazi Nooghabi, Henrik R. Thomsen, Bao Zhao +1
In this work, the Schwarz primitive unit cell is used as the building block of different types of metastructures for steering and focusing elastic vibrations. The emergence of a Br…
Boundless metamaterial experimentation: physical realization of a virtual periodic boundary condition
Henrik R. Thomsen, Bao Zhao, Andrea Colombi
We experimentally implement a virtual geometric periodicity in an elastic metamaterial. First, unwanted boundary reflections at the domain ends are cancelled through the iterative…
Fluid-loaded metasurfaces
E. A. Skelton, R. V. Craster, A. Colombi +1
We consider wave propagation along fluid-loaded structures which take the form of an elastic plate augmented by an array of resonators forming a metasurface, that is, a surface str…
Seismic metasurfaces: Sub-wavelength resonators and Rayleigh wave interaction
D. J. Colquitt, A. Colombi, R. V. Craster +2
We consider the canonical problem of an array of rods, which act as resonators, placed on an elastic substrate; the substrate being either a thin elastic plate or an elastic half-s…
