Marseille, France – Researchers from CNRS at the Fresnel Institute in Marseille have designed a device that isolates the most devastating seismic waves. Based on mathematical models, this “invisibility cloak” could equip schools and hospitals by allowing them not to feel the effects of an earthquake.

The “invisibility cloak” is a thin plate, structured to control the spread of some airwaves diverting an obstacle. Thus, an object placed at the center of the plate will not be affected by these waves, but simply bypassed. The Protection is presented in the form of concentric rings made up of various materials. The unit consists of materials which possesses novel properties, not found in a natural material.

However the invisibility cloak does not divert all types of seismic waves. The surface wave, of a magnitude generally stronger than the other, produce the most destructive earthquakes. It is primarily for the purpose of combat that researchers at the Fresnel Institute have designed the device. They have nicknamed it “invisibility cloak.”

Its application against earthquakes still requires a lot of work to adapt to the constraints of ground. On a smaller scale, the cape can remove annoying vibrations in automotive and aerospace industries.
