| Invisible Man |
Researchers from University of Texas at Austin now have figured out how to "cloak three dimensional object standing in free space", means the object is invisible. This is not like cloaking research before thats more like mimicry , using Meta-materials that bent ray of light around an object to conceal it, but only worked in two dimensions. Or device that played trick by harnessing the mirage effect to make objects behind it “disappear.”
In daily life we can see objects because the lights bound off it and eyes process the info from lights that hitting eyes. This research published this week in the New Journal of Physics, uses "plasmonic meta-materials" to make an 18-inch cylindrical tube invisibly. To put it simple this object channeling lights around the object, with designed structures that bounce ligth like a pinball machine. This why it can be invisible from every angle.

| Tested variate wavelengths to objects |
Sounds incridible with those explanations, but researchers only make it with high-frequency wavelengths, such as microwave. Researchers still troubled with optical wavelengths - what human eyes could capture it.
