Abstract
An elastic wave cloaking lattice-based metamaterial for cloaking an object within a void includes a lattice of connected unit cells arranged to form a void, each unit cell comprising a mass and a plurality of connecting springs, the mass coupled by the plurality of connecting springs to masses in adjacent unit cells, the plurality of connecting springs comprising at least two large springs of a first length and at least two short springs of a second length, the first length greater than the second length, the springs and masses having relational and mechanical characteristics to facilitate elastic wave cloaking in the totality of the lattice. The lattice as a whole has metamaterial properties resulting from the positional relationship and mechanical properties of masses and connecting springs of the unit cells such that the lattice at least partially cloaks an object or material portioned within the void from elastic waves.
