RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Metamaterial Cloak - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

-- Amateur Radio

-- Antennas

-- CAE, CAD, & Software

-- Circuits & Components

-- Employment & Interviews

-- Systems

-- Test & Measurement

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,

imodelit Moderator

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,
