Surface Plasmon Polariton Pumped Explosives Sensors
Abstract
OK State Univ proposes a new and novel electronic AN sensor design that incorporates their provennanospring-based detection with their newly developed plasmonic corrals. The plasmonic corral consists of Au pyramids oriented in a circle and other geometries of our choosing. The role of the plasmonic corral is two-fold: (1) to serve as a high intensity source of surface plasmon polaritons (SPP) and (2) a geometric structure that amplifies the density of excited metastable stable states in the GaN in the interior of the corral, similar to the quantum corral of atoms that localize electron wavefunctions in the interior of the corral. For the quantum corral, electron wavefunction interference/resonances takes place on a length scale of a nanometer or less. In the case of SPP, interference/resonance effects take place over hundreds of microns, which is well within the length scale of a plasmonic corrals. The AN sensors will consist of either a single plasmonic corral or an ensemble of them. They plan to explore both options.
