Revolutionary Smart Material Prototype Defies Newton's Laws.

Researchers at the University of Missouri have developed a prototype metamaterial that uses electrical signals to control both the direction and intensity of energy waves passing through a solid material. The metamaterial has odd mass density, which provides an unconventional way to customize the design of an object's structural dynamics, or properties to challenge Newton's second law. Potential applications include military and commercial uses, such as controlling radar waves or managing vibration created by air turbulence from an aircraft in flight.
