Make Your Own Invisibility Cloak With a 3D Printer

cylonlover writes "Invisibility cloaks have been around in various forms since 2006, when the first cloak based on optical metamaterials was demonstrated. The design of cloaking devices has come a long way in the past seven years, as illustrated by a simple, yet highly effective, radar cloak developed by Duke University Professor Yaroslav Urzhumov, that can be made using a hobby-level 3D printer."

You will see him hiding behind a big off-white disc with holes in it. Call me a nitpicker, but to me "invisible" is the opposite of "visible", which is the defining characteristic of what we call visible light. Being being undetectable to 10GHz frequencies, while impressive in its own light (haha), is most certainly not invisibility.

Well, it's invisible to that spectrum. And if you're invisible to radar, it is a limited form of 'invisible'.

Besides, inradarible sounds stupid. :-P
