The realization of topological rainbow trapping provides significant potential for applications in energy storage and recovery, signal sensing, related fields. Most studies focus on the first bandgap valley phononic crystals, which presents a challenge developing multi-band acoustic devices. This study designs three-legged circular rod crystal, where spatial symmetry is broken through rotation to open two Dirac cones. It observes edge states within ranges original bandgaps by combining...
This work presents a high-sensitivity solution sensor based on phoxonic crystal nanobeam with lateral fins. The fins improve the stability of suspended and its detection performance is unaffected. Acoustic–optic dual-mode cross-detection improves accuracy over single-mode method. acoustic optical energies are concentrated in defect slot regions due to combination gradient cavity slot, which enhances acoustic–optic interaction object be measured, improving sensitivity. Using mode bandgaps...
