A Gaussian electromagnetic wave is incident on a dense array of very thin wires (or rods). The distance between the rods and, thus, the rod diameter is much smaller than the wavelength. Under these circumstances, the rod array does not function as a diffraction grating (see the Plasmonic Wire Grating model). Instead, the rod array behaves as if it was a continuous metal sheet for light polarized along the rods. For light polarized perpendicular to the rods, the array is almost transparent to the electromagnetic wave. In the latter case, dipole coupling between the rods also results in electromagnetic excitation between the rods outside of the illuminated region.
