We calculate and visualize the degree of chirality to identify regions with relatively high values. This leads to design principles for a simple utilization of chiral fields. We investigate planar geometries which offer a convenient way to access the designated fields as well as three-dimensional nanostructures which show a very high local optical chirality.eninfo:eu-repo/semantics/openAccessOptik , Chirale Symmetrie , Simulation530Plasmonics , Metamaterialsarticle
