Protecting coastlines and generating wave power by reflecting or absorbing 90 per cent of wave energy
Xinhua Hu and colleagues at Fudan University in Shanghai, China, have come up with a way to create shield against water waves that, unlike Enoch and Guenneau's set-up, could also double up as a wave-energy plant. Hu's team proposes using a rectangular array of stationary cylinders fixed to the sea floor in coastal waters. "The resonating cylinder array that we studied can be seen as a type of metamaterial for water waves," Hu claims.
