Abstract：Overview of recent results on enhanced optical transmission(EOT) through nanostructured arrays of annular apertures (AAA) made in metallic film will be presented. Both vertical and slanted apertures are numerically, theoretically and experimentally studied. Various aspects of enhanced optical transmission (EOT) of sub-wavelength dimensions annular aperture arrays (AAA) are investigated, the results are in agreement with the theoretical results, enhanced transmission based on the excitation of the cutoff-less fundamental guided mode TEM (Transverse Electric and Magnetic) through both AAA and SAAA structures. We will also show some properties of these structures in view of potential applications in various fields.
