-The cloak! Put the cloak on!
-Dragons! That's the first task! ...
-Where magic goes early, science's not far behind. Some researchers are a step closer to making that invisibility cloak a reality. A group in Duke University figured out how to make objects invisible to microwaves. They use a coil to fudge the cross. And their work might have some practical uses pretty soon. David Schurig is an engineer in Duke, one of the inventors of this new technology, thank you very much for joining us.
-Thanks for having me on.
-Well, tell me about this. I understood it's not like the cloaks of invisibility the military uses, how does it differ?
-------------------1----------------------
-So you wouldn't see what's behind it?
-If you look directly at it, you see what's behind it. And that's the unique thing about this new tech, clocking technology.
-So that's exactly what you will do. You'll be able to cloak something and when you looked at that object, you would see what's behind it, leading the beliefs that there's nothing in between.
-Exactly. It's an effect similar to what happens in a mirage (n.海市蜃楼) where thermal gradients (热梯度) in the air banned light, rays, in a similar way. And the view ahead of the road sig is cloaked behind the image of the sky.
-So, how, I mean if you would, just a saying, put a decade on it, how many decades before we have something that is like a Harry Potter type cloak, you know, invisibility cloak?
-----------------------2------------------------
-It's gonna take a number of years to learn what nanofabrication (纳米制造) even means. Thank you very much. We appreciate this update and a lot of people gonna keep on watching this. Thank you. (All right. Thank you.) David Schurig from Duke University.

我的答案~
Well, I brought one with me to show. And here it is. and first, as you mentioned it’s designed work for microwave, so you can see it.with your naked eye. It’s different than what the military uses. And that traditional skills technology only reduces the reflection of waves that instantly on the object. But they don’t do anything about reducing the *****. This object, when microwaves are instantly on it, they’re guided around the central region where you can hide something and reformed on the foreside. So these waves looked as if they travel through free space.
Well, there’re numerous things we need to change from here to there. One is, this is a rigged shell and it’s relatively thick. It’s not a fabric you could easily wear. Those things could probably be fixed in a number of decades. Well, what may not be fixed as easily is to go to the visible light’s bedroom from the microwave’s bedroom. That’s a serious ****** challenge and that may take a number of years.
