    "abstract": "The effect of the tilt angle of metal film on the transmissivity of\nsubwavelength holes in optically thick metal film is investigated. The\ntransmission efficiency is found can be highly dependent on the tilt angle. It\nis also found that when the input photons are polarized not along the eigenmode\ndirections of surface plasmon polariton, a birefringent phenomenon is observed\nwhen the array with periodic of subwavelength holes is tilted. Linear\npolarization states can be changed to elliptical polarization states and a\nphase can be added between two eigenmodes. The phase is changed with the tilt\nangle. A model based on surface plasmon polariton eigenmodes degeneracy is\npresented to explain these experimental results.",
