I'm not sure the definition given here is precise. The EOT is first of all the enhanced transmission through subwavelength apertures arranged in a periodic way. the transmission is usualy compared to the theoretical transmission efficeincy given by Bethe-Bouwkamp model: ~(d/lambda)^4. and if the design of the periodic pattern i s successful, one can see an enhancement of ~1000. what is described here is another effect called beaming due to corrugation around a subwavelength aperture. --Mmrejen 11:32, 6 February 2007 (UTC)[reply]

2nd correction

[edit]

I do agree with the previous comment, EOT is the enhancement of the field related to the field at the aperture and beaming as a property than one can encounter by additional structuring. In additon it is evident that surface plasmon plays the fundamental role in performing subwavelength transmission. I strongly recomment modifying of this work.

3rd correction

[edit]

I agree with previous corrections, and attempted to edit the description to make it more precise. I don't know how to put in the Bethe-Bouwkamp equation described above for the description of classical aperture theory. Also, a description of the momentum-satisfying condition from grating SPR theory would be helpful: k0 = kSP + i(Gx) + i(Gy), where k0 are the free space wavevector, kSP is the surface plasmon wavevector, i and j are lattice indices, and Gx and Gy are lattice constants. —Preceding unsigned comment added by 129.74.163.96 (talk) 18:31, 25 August 2009 (UTC)[reply]

Picture of the metal film?

[edit]

I think it would be good if the article had a picture showing one or more examples of the perforated metal film described. --TiagoTiago (talk) 02:49, 5 November 2011 (UTC)[reply]
