Experimental Observation of Topologically Protected Helical Edge Modes in Patterned Elastic Plates
Topologically protected waves in classical media provide unique opportunities for one-way wave transport and immunity to defects. Contrary to acoustics and electromagnetics, their observation in elastic solids has so far been elusive because of the presence of multiple modes and their tendency to hy...
