Non-Hermitian physics describes an open system, which is susceptible to loss or gain and has been recently used to demonstrate unusual physical phenomena in non-trivial topological systems. Here, the authors investigate the physics of impurity effects in non-Hermitian, non-reciprocal lattices and discuss how the results can be realised using an electrical circuit.
