Fabrication and characterization of 2D phononic crystals based on lithium niobate substrate and nickel pillars

Résumé

This work presents experimental investigation of interaction between surface acoustic waves and 2D surface Phononic crystals (PnCs). The PnC is made of 2D array of resonant nickel pillars arranged in different symmetric lattices, and deposited on lithium niobate (Y128 cut) substrate. Measurement of transmission spectra (amplitudes and phases) was exploited to demonstrate the existence of opening band-gaps originating from local resonance.
