Model ID: 12665

A Gaussian electromagnetic wave is incident on a dense array of very thin wires (or rods). The distance between the rods and, thus, also 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, whereas for light polarized perpendicular to the rods, the array is almost transparent to the electromagnetic wave. However, for the latter case dipole coupling between the rods occurs, thereby coupling electromagnetic excitation between the rods also outside of the illuminated region.
