Experimental Demonstration of Nanoscale Pillar Phononic Crystal-Based Reflector for Surface Acoustic Wave Devices

Experimental Demonstration of Nanoscale Pillar Phononic Crystal-Based Reflector for Surface Acoustic Wave Devices

This article presents an investigation into the use of nanoscale phononic crystals (PnCs) as reflectors for surface acoustic wave (SAW) resonators, with a focus on pillar-based PnCs. Finite element analysis was employed to simulate the phononic dispersion characteristics and to study the effects of...
