Talk:Extraordinary optical transmission

From Wikipedia, the free encyclopedia

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)

[edit] 2nd correction

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.
