WAVE MANIPULATION. "The very long wavelengths of earthquake waves would be shortened as they interact with the metamaterials; the waves would pass around the building so as to arrive in phase as the earthquake wave proceeded, as if the building was not there." https://lnkd.in/eiREs7m View in LinkedIn

WAVE MANIPULATION. "Computations showed that seismic waves traveling toward a building, could be directed around the building, leaving the building unscathed, by using seismic metamaterials." https://lnkd.in/eiREs7m View in LinkedIn

BREAKTHROUGH. "A recent study reporting the use of standing sound waves for 3D graphic printing was hailed as a major breakthrough." https://lnkd.in/eN74kab View in LinkedIn

INVISIBLE BUILDINGS. "We’ve cloaked against radar, microwaves, acoustic waves, light waves, and more, but what about seismic waves? Scientists have now found a way to make buildings “invisible” to the destructive force of earthquakes." https://lnkd.in/eDGkPz8 View in LinkedIn

"ACOUSTIC BOTTLE BEAMS might also serve another application that ranks among the hottest in the high-tech community these days – acoustic levitation, in which sound waves are used to lift and manipulate millimeter-sized objects, including particles, microorganisms and droplets of water." https://lnkd.in/eN74kab View in LinkedIn

AN INGENIOUS APPLICATION of invisibility cloaking is to apply this technology to energy waves resulting from seismic earthquakes, and by positioning a giant diffraction grating or crystal structure around buildings or bridges, those waves may be diffracted or bent around the building, saving it from the force of the earthquake.

ACOUSTIC LEVITATION "is a method for suspending matter in a medium by using acoustic radiation pressure from intense sound waves in the medium. Sometimes ultrasonic frequencies can be used to levitate objects, thus creating no sound heard by the human ear, such as was demonstrated at Otsuka Lab, while others use audible frequencies." https://lnkd.in/e2nki6q View in LinkedIn

SUSPENDED CHEMISTRY. "These giant acoustic traps could lead to new technologies and devices for a variety of applications in chemistry, materials, as well as biosciences...For example, by creating this three-dimensional bottle-like acoustic trap, we could use it as a micro-chemical reactor and manipulation of biological trafficking devices." https://lnkd.in/eN74kab View in LinkedIn

DARPA, of course, is interesting in acoustic cloaking for military applications. "This effort will use directed ultrasound technology to enable the capability to significantly reduce sound emissions from large scale tactical military hardware." https://lnkd.in/bZG9Gkr View in LinkedIn
