Metamaterial Cloak - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.

Best Regards,
