Extraordinary transmission through planar quasicrystal

Extraordinary transmission through planar quasicrystal

In this paper we report the first observation of extraordinary transmission through a planar quasicrystals - 2D-quasiperiodic arrays of subwavelength holes. Our experiments were performed both in the microwave (30 - 1.5 cm) and optical (450 1700 nm) parts of the spectrum. In the microwave region we studied both supported by a dielectric substrate and free-standing perforated metal films, while in the optical part a large quasicrystal array of holes in a supported aluminium film has been investigated. We show that the observed series of extraordinary transmission peaks are associated with the maxima of the Fourier transform of the quasicrystal lattice. This indicates that divergence-like behaviour in the reciprocal space is sufficient for extraordinary transmission to appear. Our work paves the way towards the tailoring of hole-array transmission properties, whereby transmission peaks at on-demand wavelengths and angles of incidence can be achieved.

Abstract

Light transmission through periodic subwavelength hole arrays was shown to be extraordinary at wavelengths related to the periodicity of the arrays and ultimately expressed in terms of their reciprocal lattice vectors [Nature 391,667 (1998)]. In this paper we report the first observation of extraordinary transmission through a planar quasicrystals - 2D-quasiperiodic arrays of subwavelength holes. Our experiments were performed both in the microwave (30 - 1.5 cm) and optical (450 1700 nm) parts of the spectrum. In the microwave region we studied both supported by a dielectric substrate and free-standing perforated metal films, while in the optical part a large quasicrystal array of holes in a supported aluminium film has been investigated. We show that the observed series of extraordinary transmission peaks are associated with the maxima of the Fourier transform of the quasicrystal lattice. This indicates that divergence-like behaviour in the reciprocal space is sufficient for extraordinary transmission to appear. Our work paves the way towards the tailoring of hole-array transmission properties, whereby transmission peaks at on-demand wavelengths and angles of incidence can be achieved.
