Agora for month of November

Posted on 07/11/2011 by
Dear all,
 
We will start our optica agora regular session from the coming wednesday i,e 9th of november. Silvania has suggested the paper related to perfect imaging (without Pendry contributions !!).
 
Silvania will chair the session. For the first two weeks we will disuss the first paper and then the second paper in the last two sessions.
The papers to be discussed are:
 
First paper: U. Leonhardt, Perfect imaging without negative refraction, New journal of physics 11 093040, 2009
 
 
Second paper (experiment) Evidence for subwavelength imaging with positive refraction New Journal of Physics 13 033016, 2011 
 
regards,

Agora “March”

Posted on 08/03/2011 by

from Jeff:

For the month of March I was hoping we could discuss the emerging field of Antenna technology applied to optical frequencies. I found this review paper by Bharadwaj et. al. which I’d suggest you start reading. It’s rather long so if you get 1/3 way through it that’s fine. Or if you understand the first 8 or 10 equations you can just stop there and explain them to me 😉

Also, if you have been involved in this field or done any reading on it, I’m particularly interested in your input. Personally I have a good background in classical antenna theory, but no background in quantum mechanics, so parts of this paper went over my head. But hopefully we can concentrate more on qualitative descriptions and applications.

I had a lot of trouble downloading this paper, you can find in the Scratch (the previous link has been removed)

See you all Wednesday at 12:30 (or 13:00 if you want to miss lunch 😉

Posted on 18/02/2011 by

Dear all,

For the last session of Optica agora for this month, I propose to read the following paper.

"Nanometric resolution using far-field optical tomographic microscopy in the multiple scattering regime". The following paper can be found at

Agora in 2011

Posted on 31/01/2011 by

 Dear all,

The first session of Optica Agora of 2011 starts on 2nd February at 12.15pm in our optics library room E009. 

We are going to discuss  the paper on phase retrieval from intensity measurements in optics, for the first two weeks and then for the last two weeks we will discuss RCWA method applied to optical cases particularly grating.. For the first session (2nd february) we will discuss the first four sections of the following paper

"Phase retrieval algorithms: a comparision" by J.R. Fienup.

It can be found here
