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…
Small-World Disordered Lattices: Spectral Gaps and Diffusive Transport
Matheus I. N. Rosa, Massimo Ruzzene
We investigate the dynamic behavior of lattices with disorder introduced through non-local network connections. Inspired by the Watts-Strogatz small-world model, we employ a single…
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…
Amplitude-dependent edge states and discrete breathers in nonlinear modulated phononic lattices
Matheus I. N. Rosa, Michael J. Leamy, Massimo Ruzzene
We investigate the spectral properties of one-dimensional spatially modulated nonlinear phononic lattices, and their evolution as a function of amplitude. In the linear regime, the…
