Transmission efficiency and localization length are significant characteristics for topological waveguides to design functionalities. Such characteristics depend on the topological boundary geometry. In this presentation, we will introduce the experimental and numerical results of the propagation and localization characteristics in the quantum valley-Hall-based elastic topological waveguides consisting of three different boundary geometries.
