Phys. Rev. Lett. 103, 203901 (2009) [4 pages]How Holes Can Obscure the View: Suppressed Transmission through an Ultrathin Metal Film by a Subwavelength Hole ArrayReceived 5 August 2009; published 9 November 2009 If a metal film, thick enough to be totally opaque, is perforated by tiny subwavelength holes in an orderly fashion, the transmission will be enhanced extraordinarily [ T. W. Ebbesen et al. Nature (London) 391 667 (1998)]. Here, we investigate the transmission through an ultrathin semitransparent Au film with a square array of subwavelength holes and observe the opposite behavior: less light is transmitted through the pierced metal compared to the closed film. © 2009 The American Physical Society URL:
