Graded Plasmonic Metagratings for Directional Nonlinear Optical Sensing
Advanced Optical Materials, EarlyView.A refractometric sensing approach is presented, based on the angular variation of the emission pattern while changing the local environment. This method is first demonstrated on rectangular arrays, then on an aperiodic metagrating configuration designed to shape the first diffraction orders into a broadened band. Abstract Plasmon‐enhanced sensing based
