[HTML][HTML] Pushing the limits of complete omnidirectional bandgaps in 2D nonsymmorphic single-phase phononic crystals

I Nadejde, EL Thomas, PI Galich - Applied Physics Letters, 2023 - pubs.aip.org
We expand the limits of complete omnidirectional bandgaps (neither P-nor S-waves can
propagate) for high symmetry two-dimensional phononic crystal (PnC) designs. We reveal …

[HTML][HTML] Mechanisms of bandgap formation in 2D single-phase phononic crystals with 4-fold rotational symmetry

I Nadejde, PI Galich - Journal of Sound and Vibration, 2025 - Elsevier
We investigate the formation mechanisms of bandgaps (BGs) in 2D phononic crystals
(PnCs) with 4-fold rotational symmetry, focusing on the symmorphic p4 and p4 mm, and the …

[HTML][HTML] Acoustic metasurfaces with Frieze symmetries

DB Moore, TA Starkey, GJ Chaplain - The Journal of the Acoustical …, 2024 - pubs.aip.org
Frieze patterns follow a set of tiling instructions including reflection, rotation, and translation,
and tile the infinite strip. Many metamaterials function due to the underlying symmetry, and …

[PDF][PDF] Enhanced Vibration Attenuation in p4gm Phononic Crystals Via Coupled Bragg and Local Resonance Bandgaps

I Nadejde, PI Galich - 30th International Congress on Sound and …, 2024 - researchgate.net
Phononic crystals (PnCs) are periodic materials based on particular geometric designs that
create a periodic impedance contrast. PnCs can attenuate elastic waves at various …
