First 3D Metamaterials will enable higher resolution ultrasound, stealth submarines and other applications
Researchers have developed the first three dimensional metamaterials by combining physico-chemical formulation and microfluidics technology. This is a new generation of soft metamaterials that are easier to shape. In their experiment, the researchers got ultrasonic oscillations to move backwards while the energy carried by the wave moved forwards. Their work opens up new prospects, especially …
