E-Mail Metamaterials that can control the refractive direction of light or absorb it to enable invisible cloaks are gaining attention. Recently, a research team at POSTECH has designed a metasurface that can control the acoustic or elastic waves. It is gaining attention as it can be used to escape from threatening earthquakes or build submarines untraceable to SONAR. Professor Junsuk Rho of POSTECH s departments of mechanical engineering and chemical engineering and Ph.D. candidate Dongwoo Lee of the Department of Mechanical Engineering in collaboration with Professor Jensen Li of HKUST have designed an artificial structure that can control not only the domain of underwater sound but also of vibration. The research team has presented an underwater stealth metasurface independent from SONAR by controlling the acoustic resonance to absorb the wave. They also confirmed that the wave propagation through a curved plate, such as vibrations, can be drastically altered; and have ....
