Strong nonlocalization induced by small scale parameter on terahertz flexural wave dispersion characteristics of a monolayer graphene

►Strong effect of nonlocality on flexural wave in a monolayer graphene is captured. ►Flexural wavenumber escapes to infinite at certain frequency. ►Localization and stationary behavior is observed. ►Cut-off frequency of depends on axial wavenumber and nonlocal scaling parameter. ►A new frequency (escape frequency) is observed in nonlocality.
