Figure Legend:
Dispersion relation of surface plasmon-polaritons in a (kx,ky) plane for a fixed frequency on a grating. The radius of the dashed circle is the wave vector modulus in free space. Inside this circle (in gray), the emitted waves have a real z-component of k, so that they are propagating waves. Outside the dashed circle, the waves are evanescent waves. The solid circle at the center has a radius equal to the modulus of the wave vector of the surface plasmon-polariton kSP. With a grating of period Λ, this solid circle is reproduced with a period 2π∕Λ: It represents the surface waves diffraction at the orders ±1. One can see that a part of the solid line is lying now in the light cone, so that the corresponding surface plasmon-polaritons are coupled to propagating waves.

Figure Legend:
Solid line: Schematic dispersion relation of a surface plasmon polariton. Dashed line: Light cone. The solid curve lies out of the light cone, so that the wave is evanescent. k‖ is the projection of the wave vector in the plane (x,y), and ω=2πc∕λ is the pulsation.

Emission of a grating in the direction (θ,ϕ). The electric field E makes an angle Ψ with the plane (z,k). Ψ=0deg corresponds to the p-polarization and Ψ=90deg to the s-polarization.
