[Material] National Taiwan University Presents Innovating Materials with Wide Range of Application in Energy, Environment and Medical Equipment, Published in Science (Chinese Version)

NTU Newsletter (Issue 1026) A five-member research team, including Distinguished Professor Din Ping TSAI, Department of Physics and Graduate Institute of Applied Physics, National Taiwan University, and Professor Nikolay I. ZHELUDEV, Deputy Director (Physics) of the Optoelectronics Research Centre at the top university in optoelectronics in UK, University of Southampton, has just published their findings about toroidal dipolar response in metamaterial in the November 5 Issue (November 4 online) of Science. The article has drawn international attention. With an innovating idea and the precise manufacturing and measuring skills, the team successfully invents toroidal metamaterial and contributes an direct experimental evidence that the toroidal artificially engineered medium can be made into highly applicable metamaterials, creating a new domain of artificial metamaterials design and manufacturing.

The characteristics of the natural materials are determined by the atomic oscillations pattern of the atoms and particles that constitute them. The artificially engineered metamaterial with toroidal structure possesses a highly applicable electromagnetic oscillation effect and amplification effect. The toroidal coil can be used as the artificially designed atoms (artificial atom) and it then can provide electro-optically operative conditions for human beings to control metamaterials. Professor Din Ping TSAI at National Taiwan University, and the National Applied Research Laboratories are now trying to develop applications of such a metamaterial to energy equipment, environmental equipment and medical equipment.

"Metamaterials" is an emerging topic during the past few years. They are different from traditional materials for their characteristics are not determined by the elements of the materials themselves but by the internal artificially designed structure. Recent developments in this field include "perfect lens", "super lens", "negative refraction", "invisibility cloak", etc.
