Abstract
This article presents the strong, nonlocal scale effect on the terahertz flexural wave dispersion characteristics of a monolayer graphene sheet (GS), which is embedded in elastic medium. The chemical bonds are assumed to be formed between the GS and the elastic medium. From the spectrum analysis, we found that the elastic matrix highly affects the flexural wave mode and rapidly increases the frequency band gap of flexural wave. The nonlocal elasticity calculation shows that the wavenumber escapes to infinite at a certain frequency and the corresponding wave velocity tends to zero at that frequency, indicating localization and stationary behavior.
