Edge modes for flexural waves in quasi-periodic linear arrays of scatterers

open access: yesAPL Materials, 2021
We present a multiple scattering analysis of robust interface states for flexural waves in thin elastic plates. We show that finite clusters of linear arrays of scatterers built on a quasi-periodic arrangement support bounded modes in the two-dimensional

High-quality resonances in quasi-periodic clusters of scatterers for flexural waves

open access: yesAIP Advances, 2022
Multiple scattering theory is applied to the study of clusters of point-like scatterers attached to a thin elastic plate and arranged in quasi-periodic distributions.
