%X Numerical simulation has been performed on the optical transmission enhancement of a metallic film with a two-dimensional subwavelength hole array- The results show that the ideal conducting film of the same array structure also presents a transmission enhancement, but the enhancement is not higher than that of the real one- Further analysis reveals that a complicated waveguide coupling effect is responsible for the enhanced transmission- The excitation of surface current on metallic surface transfers the light energy of incidence from metallic surfaces to the holes and then adjusts the optical transmission- We believe that the resonant excitation of surface plasmon is not necessary for the enhancement effect-
