Dear all,

I'd like to share with you some collected data about "Metamaterial Cloak". These data are collected from several websites and forums. I've uploaded them on http://imodelit.com/Sharewarelist.aspx?CAT_ID=140&ISShareWare=1.
Kindly, check these papers and let us open a discussion on them. Thanks.

Best Regards,

Greetings:

Here is a new article that appeared on the Science Daily website describing an optical wavelength metamaterial cloak.

Dear Kirt,

I have a small question about the article you sent its URL. The article said that they built a negative refractive index using a "Horse shoe shape nano-wires", how that will give a negative refractive index? By analogy to the SRR structures, SRRs give negative permeabilty only, and inorder to get negative refratctive, wires are added to get negative permitivity. Thanks in advance.
