Sharp features are observed in the wavelength-dependent reflectivity of very deep highly blazed zero-order metallic gratings at microwave frequencies. These features are attributed to the resonant excitation of self-coupled surface plasmon polaritons in the cavities of such samples. The slat structures may, in a simplistic model, be treated as a class of Fabry–Pe´rot cavity resonator. © 2001 American Institute of Physics.

    Nanometric optical waveguides can be made by using the dependence of surface plasmon polaritons on the gap-width between two parallel metallic plates. This waveguide can be called surface plasmon polariton gap waveguide (SPGW). The H-plane and E-plane optical circuits that consist of SPGWs have...

It is shown that this process strongly depends on the refractive indices of dielectrics surrounding the metal layer. The possibilities of high-speed optical signal...
