Mechanics and dynamics of two-dimensional quasiperiodic composites
Danilo Beli, Matheus I. N. Rosa, Carlos De Marqui +1
Periodic configurations have dominated the design of phononic and elastic-acoustic metamaterial structures for the past decades. Unlike periodic crystals, quasicrystals lack transl…
Exceptional points and enhanced sensitivity in PT-symmetric continuous elastic media
M. I. N. Rosa, M. Mazzotti, M. Ruzzene
We investigate non-Hermitian degeneracies, also known as exceptional points, in continous elastic media, and their potential application to the detection of mass and stiffness pert…
Experimental observation of temporal pumping in electro-mechanical waveguides
Yiwei Xia, Emanuele Riva, Matheus I. N. Rosa +4
We experimentally demonstrate temporal pumping of elastic waves in an electromechanical waveguide. An aluminum beam covered by an array of piezoelectric patches connected to shunt…
Topological Gaps by Twisting
Matheus Rosa, Massimo Ruzzene, Emil Prodan
It is shown that twisted -layers have an intrinsic degree of freedom living on -tori, which is the phason supplied by the relative slidings of the layers and that the twist…
Dynamics and topology of non-Hermitian elastic lattices with non-local feedback control interactions
Matheus I. N. Rosa, Massimo Ruzzene
We investigate non-Hermitian elastic lattices characterized by non-local feedback control interactions. In one-dimensional lattices, we show that the proportional control interacti…
