Abstract

Non-Hermiticity (material damping) intrinsically exists and can possibly drive the topological phase transition. Here, we utilize the perturbative elastic metamaterials to prove that appropriately tailored non-Hermitian modulation can induce topological edge states to appear not only in the topological bandgap but also in the continuous bulk spectrum.
