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…
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…
