Abstract

Systems and methods according to present principles provide ways to construct and use tunable exceptional point (EP) singularities in three-dimensional plasmonic nanostructures. Such structures have applications in sensing, communication, imaging, and other fields where, e.g., determining sub wavelength features of interest is of value.
