Measurement of a Topological Edge Invariant in a Microwave Network
We report on the measurement of topological invariants in an electromagnetic topological insulator analog formed by a microwave network, consisting of the winding numbers of scattering matrix eigenvalues. The experiment can be regarded as a variant of a topological pump, with nonzero winding implyin...
