An ‘invisibility cloak’ for tsunamis?

A tsunami is headed right for a vulnerable shallow-water gas platform. The next minute, the first wave passes by harmlessly as if the structure had completely disappeared. Impossible? Perhaps not, according to a team of French and British physicists that has devised an ‘invisibility cloak’ that could, in theory, hide susceptible platforms or coastlines from ocean waves such as tsunamis. … The cloaking concept is based on positioning multiple rows of pillars at specific intervals within a cylindrical pattern, so that the pillars and intervening spaces resemble a round checkerboard from above. In the lab, a small aluminum cylinder was subdivided into 50 precisely spaced rows of pillars radiating out from a flat center. The columns essentially dissipate oncoming waves so that anything behind the structure is hidden from them. Maybe even from tsunami waves. – msnbc
