Fully Polarized Topological Isostatic Metamaterials in Three Dimensions
Topological surface states are unique to topological materials and are immune to
disturbances. In isostatic lattices, mechanical topological floppy modes exhibit softness …

Spectral energy scattering and targeted energy transfer in phononic lattices with local vibroimpact nonlinearities
We propose a method for manipulating wave propagation in phononic lattices by employing
local vibroimpact (VI) nonlinearities to scatter energy across the underlying linear band …
