Today we continue with our discussion about the review paper "Light in Tiny Holes".
We restart from page 41 "single apertures surrounded by periodic corrugations"

We have forgotten to put the picture of the Agora Chairman of the month of May. Here it is Alberto!

In the last Agora we started to discuss about the review paper "Light in tiny holes". We saw that the first attempt to describe such problem was made by Bethe in early 40’s. However, the theory fails when compared to recent experimental results. The problem was that the Bethe’s theory considered an infinitly thin metal layer, which is a strong idealization. When we considered the effects of a hole in a metal layer with thickness ‘d’, we realized that ‘surface plasmons’ started to play an important role in the problem’s analysis. Therefore, we decided to get a better understanding in this subject. So, for the next week, bring your contribution to the "surface plasmon" discussion. After that, we continue on the paper, restarting from the box 2.

be Aware we are meeting on TUESDAY 10th of May!!!!!

 Dear all

 Alberto has found a nice paper for us at the agora. It is called "Light in tiny holes". In fact, this is a review of this subject published in nature.
The idea is to discuss what happens when light is incident in structures way smaller than the wavelength employed.
Since some of us have already experience in this field, it will be easier to discuss and share knowledge.

You can find the paper on the scratch under the name "110504 – Light in Tiny Holes" or go directly to the Link to the paper

"Light in tiny holes" by Genet, C. and Ebbesen, T. W.
Nature, Volume 445, Issue 7123, pp. 39-46 (2007).

Be all there at 12.15 tomorrow!

Dear all, 

the next agora will be given at 12.15 on wednesday the 4th of May 2011. Alberto will be the speaker. He will give us the paper to ready tomorrow!
