With active cloaking, three devices placed around an object neutralize and later rebuild the waves directed at it

Article Summary

Mathematicians at the University of Utah have recently announced they have elaborated an innovative way to shield two-dimensional objects from all types of waves, from electromagnetic to those caused by natural events like earthquakes and tsunamis, leading the way to a completely new approach to achieving invisibility.
