A Circular Crested Lamb Wave Resonator with Spurious Mode Suppression and Quality Factor Enhancement
Xianzheng Lu, Liang Lou, Hao Ren
To date, nearly all the reported Lamb wave resonators (LWRs) are straight crested LWRs, which suffer from inherent spurious modes and low quality factors (Q). For the first time, t…
