Abstract:
A method and system for spectroscopy of surface plasmons is presented. An electromagnetic wave is made incident on a diffraction grating. Surface plasmons are excited on a medium coincident to the diffraction grating and dispersion of a wavelength spectrum of the electromagnetic wave are simultaneously performed through diffraction. Changes in spatial distribution of intensity in the wavelength spectrum of the diffracted electromagnetic wave due to the excitation of the surface plasmons are measured.
