Abstract Wave propagation in a longitudinally curved viscoelastic structure with a large or infinite cross section is a common problem frequently encountered. To study this problem, a coupled finite element method-perfectly matched layer (FEM-PML) modelling methodology based on a curved two-and-a-half-dimensional (2.5D) formulation is proposed in ...

Transverse Spurious Mode Compensation for AlN Lamb Wave Resonators
Lamb wave modes with type I dispersion characteristics exhibit strong affinity toward multi transverse modes behavior above resonance frequency (fr) in the AlN Lamb wave resonators (LWRs), especially the high-transduction-efficiency modes: S0 and S1 mode.
