题 目：Win Some or Lose Some: A Re-look And Out-look of Metamaterials
报告人：Prof. Cheng-Wei Qiu（新加坡国立大学）
Metamaterials, derived from transformation optics or negative refraction law, have been receiving intensive attention. Exciting progress has been made to pave the way from fundamental physics to real-world devices, exhibiting unprecedented light phenomena, such as cloaking, super-resolution, focusing, redistribution of photon momentum, etc. In this talk, we will present an alternative look into the realm of non-metamaterials, and see whether they can perform as equally well as, if not better than, the metamaterial counterpart. In particularly, we will demonstrate back-to-back comparative results in cloaking, focusing, super-resolution, and tractor beam, including our very recent results published or to be published. Interestingly new phenomena can be found in classic methods or materials which can definitely compete with its counterpart in metamaterials. Nevertheless, it again proves the universal truism that neither of these two routes is perfect.
