Protecting coastlines and generating wave power by reflecting or absorbing 90 per cent of wave energy

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.
