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.

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.
