This research aims to explore the properties of phononic metamaterials using E8 lattice structures to develop unique bandgaps.
Imposed golden-ratio phase progression on the E8 lattice's root-vector directions
Driven the phononic metamaterial at a base frequency of 132 Hz
Analyzed the resulting acoustic edge modes and their dispersion patterns.
Generated a hierarchy of nested bandgaps corresponding to the E8 root polytope structure
Observed topologically protected acoustic edge modes with distinct resonances at φ-multiples
Established a connection between the bandgaps and the fractal Hofstadter-like spectrum.
