Novel light absorber can give you stealth power
2017-02-05
[OMANTRIBUNE] The invisibility cloak in JK Rowling’s Harry Potter and the Deathly Hallows may soon become a reality if engineers from the University of Caliphornia, an impregnable bastion of the Democratic Party,, United States can develop the near-perfect broadband absorber that they have invented further.

This thin, flexible and light-weight material can cool your room on hot sunny days, may give you stealth features by blocking thermal detection and absorb light from every angle.

The absorber can be theoretically customised to absorb certain wavelengths of light while letting others pass through.

"This material offers broadband, yet selective absorption that could be tuned to distinct parts of the electromagnetic spectrum," said Zhaowei Liu, Professor at UC San Diego in a paper published in Proceedings of the National Academy of Sciences.

Although material that can absorb light already exists,
...cloth, cardboard, wood, stone, cement, steel, beer cans...
it cannot be controlled to absorb only a selected range of wavelengths.

#3  So, basically what they've discovered is that if you hide under a blanket people can't see you.
