In this work it is shown that nonreciprocal structures with continuous translation symmetry can have an ill-defined topology. In particular, it is experimentally verified that the topology of a ferrite can be effectively regularized when an air layer is adjoined to the relevant material interface. Furthermore, it is experimentally demonstrated that ill-defined topologies can be used to create energy sinks where the electromagnetic fields are massively enhanced.
