Canonical scattering problem in topological metamaterials: Valley-Hall modes through a bend

Theo Torres, Cédric Bellis, Régis Cottereau +1

We study the amount of backscattering of Valley Hall modes in a classical topological insulator. In reciprocal systems, the conservation of the valley index has been argued to be a…
