Hyperbolic-polaritons-enabled dark-field lens for sensitive detection

Abstract Sensitive detection of features in a nanostructure may sometimes be puzzled in the presence of significant background noise. In this regard, background suppression and super-resolution are substantively important for detecting weakly scattering nanoscale features. Here, we present a lens de...
