We think naturally about Harry Potter or other fantasies whenever we hear something about invisibility or invisible cloak. But, this time it is for real. According to New Scientist, a team of physicians at the Fresnel Institute in Marseille, France has serious efforts for the protection of buildings by eliminating earthquake creating seismic waves, especially surface waves which are more destructive. The other type of wave is called as body wave and not controllable as surface wave, luckily it is not as destructive as its counterpart.
According to the theory, a cloak group of large concentric plastic rings will be fixed to the Earth’s surface. When surface waves come to this re-arrangeable area, these plastic rings will keep them not going to the building and direct the waves outside. It is all about tuning to the frequency of coming waves individually.
A building which is 10 meters across will need a few plastic rings which have 1 to 10 meters diameters and 10 cm thickness in its foundation.
Invisibility cloaking has made certain progress in especially light manipulation field of physics. It is quite possible that we will see such materials in constructions as well.
Today’s fantasy is tomorrow’s reality.
