Topological rainbow trapping of elastic waves in two-dimensional valley phononic crystal plates

Applied Physics Letters, Journal Year: 2024, Volume and Issue: 124(8)

Published: Feb. 19, 2024

Rainbow trapping is a significant strategy for capturing waves of different frequencies at spatial positions. It offers potential multi-frequency on-chip nanophotonic devices in the era big data and has attracted much interest recently, topological rainbow that immune to disorder been observed optics acoustics. Reported here elastic using gradient valley phononic crystal plates (PCPs) with hexagonal lattice, based on edge states are localized boundary between two PCPs opposite phases. The achieved by gradually adjusting height scatterers or thickness PCPs. shown applying vertical vibration studied PCPs, which simple structure easily fabricated, providing good solution manipulating waves.

Sub-wavelength topological boundary states and rainbow trapping of local-resonance phononic crystal plate

Journal of Physics D Applied Physics, Journal Year: 2024, Volume and Issue: 57(22), P. 225302 - 225302

Published: Feb. 23, 2024

Abstract Based on the analogy of quantum valley Hall effect, a ligament-type phononic crystal plate with local resonators is designed in this study to facilitate state transport low-frequency elastic waves. We analyze key factors affecting resonance modes and reduce frequency Dirac cone by changing connection form structure’s beams. The spatial inversion symmetry structure broken open new band gap introducing mass difference resonator pair. robustness topological waveguide under defects bends verified. characteristic, we introduce gradient heights into supercell where waves at different frequencies split stop significantly achieve sub-wavelength rainbow trapping. This design provides theoretical reference for exploring mode application capture structures.
