a In Oxz plane at y = 0, b, in xy plane at z = −1 mm, and c, in ξy plane that is perpendicular to the propagation direction of the reflected beam (see the ξ axis depicted in a). We recall the geometric parameters: N = 7, a beam-waist W0 = 5 μm and a Transverse Electric (TE) polarized incident beam.
