Topolectrical circuits constitute a new avenue of topological states realized in a classical environment. With them, it is possible to reproduce band structures seen in models for topological insulators (TI) where the bands correspond to impedance (or admittance) eigenvalues. Because electrical circuits are more easily accessible than TIs, they are particularly suitable for studying topological states, reaching from the simplest models to non-hermitian and other types of rather “exotic” physics. In our talk, we illustrate the explicit measurement of topological band structures in the context of topolectrical circuits.
