Abstract

This work demonstrates topologically protected flexural edge states in a graphene-like elastic metamaterial plate. Numerical calculations and experiments show robust wave transport along free boundaries, with edge states appearing at zigzag boundaries without breaking time-reversal, mirror, or inversion symmetry. The paper also introduces an elastic Shannon-entropy-based measure to assess the frequency range of edge states.
