Abstract:
The roughness of shallow or deep metallic diffraction gratings modifies the propagation of surface plasmon mode along the metallic–air interface. The scattering losses lead to a spectral or angular broadening of the surface plasmon resonance (SPR) and to a shift of the resonance wavelength and coupling angle. This mechanism is deeply analyzed both experimentally and theoretically to overcome these effects when such structures, in particular deep ones, are used as SPR-based sensors.
