title: Cathodoluminescent spectroscopic imaging of surface plasmon polaritons in a 1-dimensional plasmonic crystal.
abstract: Angle-resolved measurements on a cathodoluminescence (CL) detection system equipped with a 200 keV transmission electron microscope were performed on a 1-dimensional silver grating. The dispersion curves of surface plasmon polaritons (SPPs) on the grating were derived from the angle-resolved CL spectra, and patterns of SPP standing waves at the plasmonic band edge were directly observed.
