Subwavelength topological interface modes in a multilayered vibroacoustic metamaterial
Majdi O. Gzal, Joshua R. Tempelman, Kathryn H. Matlack +1
We present a systematic and rigorous analytical approach, based on the transfer matrix methodology, to study the existence, evolution, and robustness of subwavelength topological i…
Wavenumber Scattering and Inter-band Targeted Energy Transfer in Phononic Lattices with Local Vibro-Impact Nonlinearities
Joshua R. Tempelman, Kathryn H. Matlack, Alexander F. Vakakis
We propose a method for manipulating wave propagation in phononic lattices by employing local vibro-impact (VI) nonlinearities to \textit{scatter} energy across the underling linea…
A Modal Decomposition Approach to Topological Wave Propagation
Joshua R Tempelman, Alexander F Vakakis, Kathryn H Matlack
The characteristics of topologically protected wave propagation is typically predicted via the band structure of the primitive unit cell, using Berry curvature to predict localized…
Topological Protection in a Strongly Nonlinear Interface Lattice
Joshua R. Tempelman, Kathryn H. Matlack, Alexander F. Vakakis
Mechanical topological insulators are well understood for linear and weakly nonlinear systems, however traditional analysis methods break down for strongly nonlinear systems since…
