Anisotropic Cylindrical Waves in a Square Lattice of Acoustic Waveguides
Ioannis Ioannou Sougleridis, Olivier Richoux, Vassos Achilleos +2
We investigate the propagation of cylindrical waves in a square network of acoustic waveguides. We establish, both theoretically and experimentally, the anisotropic dispersion rela…

Ring-Shaped Linear Waves and Solitons in a Square Lattice of Acoustic Waveguides
I. Ioannou Sougleridis, O. Richoux, V. Achilleos G. Theocharis +1
We study the propagation of both low- and high-amplitude ring-shaped sound waves in a 2D square lattice of acoustic waveguides with Helmholtz resonators. We show that the inclusion…
