We demonstrates the connection between the reduced rotational symmetry of a chiral structure unit-cell to the existence of the Kramers-Kronig relations between the chiral spectral parameters in the k-space and found that the reduction in rotational symmetry affects the locality condition, which unavoidably leads to the deviation from the Kramers- Kroning Further, we experimentally investigated plasmonic metasurfaces comprising topological edge states. In particular the structure was composed of two domains with an abrupt change in unit-cell geometry defining a topological dislocation. We discussed line and point dislocations with trivial and non-trivial topological phases.
