Abstract :
We investigate the extraordinary optical transmission of a subwavelength elliptic hole array in a metal by a proposed simple method. The transmission strength depends on the polarization direction of the incident light. The polarization excitation ratio of the surface plasmon polariton (SPP) governs the transmissivity. There is an interplay between the adjacent holes which is caused by the transverse magnetic filed of SPP on the surfaces of the metal.
