Interface states in two-dimensional quasicrystals with broken inversion symmetry
Danilo Beli, Matheus I. N. Rosa, Luca Lomazzi +2
We investigate the existence of interface states induced by broken inversion symmetries in two-dimensional quasicrystal lattices. We introduce a 10-fold rotationally symmetric quas…
Non-Hermitian acoustic waveguides with periodic electroacoustic feedback
Danilo Braghini, Vinicius D. de Lima, Danilo Beli +2
In this work, we investigate non-Hermitian acoustic waveguides designed with periodically applied feedback efforts using electrodynamic actuators. One-dimensional spectral (infinit…
Wave beaming and diffraction in quasicrystalline elastic metamaterial plates
Danilo Beli, Matheus Inguaggiato Nora Rosa, Carlos De Marqui +1
In this paper, we present numerical and experimental evidence of directional wave behavior, i.e. beaming and diffraction, along high-order rotational symmetries of quasicrystalline…
Space-time wave localization in electromechanical metamaterial beams with programmable defects
Renan Lima Thomes, Danilo Beli, Carlos De Marqui
A flexible wave localization is investigated using a spatial-temporal modulation of point defects along the periodic array of electromechanical local resonators of a piezoelectric…
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…
