Cloak of Invisibility Coming Soon

Posted by ryuzaki0 on from the i've-heard-that-before dept.

davaguco writes "It seems that we will finally be able to make ourselves invisible" It seems like this story resurfaces every few months and then gets submitted a zillion times so here it is. Personally I'm still waiting for my cloak of evasion. 20% miss chance is awesome.

  1. Wouldn't it be easier... by Kelson · · Score: 5, Interesting

    To create a Somebody Else's Problem field? People are quite good at ignoring what they think isn't important (or what they don't want to recognize), so if you could find a way to convince people to ignore something, it would be just as effective as actual invisibility.

    Nothing to see there. Moving right along...

    From TFA:

    Prof Milton's team calculated that when certain objects are placed next to superlenses, the light bouncing off them is essentially erased by light reflecting off the superlens, making the object invisible.

    Sounds an awful lot like the technology speculated about in Dean Ing's Ransom of Black Stealth One about ten years ago.

    Sounds like a rehash of a phase conjugate mirror.

    Maybe I'm getting this the wrong way, but if the object "absorbs" the light coming to it through the lens, wouldn't that object be perceived as black? I thought "invisible" is when any light coming behind the object passes through it, and into the observer's eye, with no obstacles whatsoever. But maybe it's just me...
  5. "Selective frequencies" already in use by the Navy by CustomDesigned · · Score: 5, Interesting

    My Dad worked on creating "custom fog" for the Navy. He studied propagation, e.g. this civilian paper. Then he developed a method of modifying droplet size distribution in fogs over the ocean. The end product (details classified) allows ships to create a fog bank on demand over large bodies of water (within 1 or 2 hours) that blocks enemy frequencies, but has "holes" for friendly scanner frequencies. The details include taking temperature/humidity/droplet profiles by altitude of the atmosphere over the target area.
