Cloaking method could protect buildings from earthquakes or tsunamis

Posted on Saturday, August 22 2009 @ 11:20:09 CEST by

DailyTech reports a researcher for the University of Utah named Graeme Milton has developed a new cloaking method that may one day be used to allow buildings and other large structures to be shielded from things like sonar, radar, earthquakes, and even tsunamis:
Milton said, "We have shown that it is numerically possible to cloak objects of any shape that lie outside the cloaking devices, not just from single-frequency waves, but from actual pulses generated by a multi-frequency source."

He continued, "It's a brand new method of cloaking. It is two-dimensional, but we believe it can be extended easily to three dimensions, meaning real objects could be cloaked. It's called active cloaking, which means it uses devices that actively generate electromagnetic fields rather than being composed of 'metamaterials' [exotic metallic substances] that passively shield objects from passing electromagnetic waves."
