Recent experimental discovery of the enhanced optical transmission through metal films with periodic subwavelength holes has given rise to a considerable interest in the optical properties of such structures due to their possible numerous applications in optics and optoelectronics as well as rich physics behind the phenomenon of the transmission enhancement [1–4]. The transmission of a subwavelength aperture is very low and proportional to the fourth power of the ratio of its diameter and light wavelength. However, if a metal film is perforated with a periodic array of such holes, the optical transmission can be significantly enhanced [1]. Being normalized to the total area of the illuminated holes, the transmission coefficient corresponds to an enhancement up to 3 orders of magnitude compared to the transmission of the same number of individual holes. This enhancement depends on the array geometry (hole diameter and periodicity), light wavelength, angle of incidence, as well as material of a film.
