Plasmon Mediated Resonant Transmission Through An Undulated Metal Film Used As Information Carrier

2008

International audience; A small amplitude sinusoidal undulation of a continuous thin metal film embedded in a homogeneous medium gives rise to an effect of resonant transmission through the excitation of the plasmon modes propagating along the film. This simple topographic feature can be used to encode high density information at the surface of an easily replicable element.
