Metamaterials and Plasmonics: a New Frontier of Science and Technology
Abstract:
Recent theory predicted a new class of meta structures made of engineered sub wavelength entities - meta “atoms” and “molecules” which enable the unprecedented optical properties that do not exist in the nature such as optical magnetism and artificial plasma. Especially, the predicted superlens made of metamaterials breaks the fundamental diffraction limit, which may have profound impact in wide range of applications such as nano-scale imaging, nanolithography, and ultra-density data storage.
I’ll discuss a few recent experiments that demonstrated these intriguing physics. We created the first bulk optical metamaterials that show the negative refractions. We demonstrated the superlens and optical cloaking using carefully design of plasmonic materials dispersions. I will further discuss a new technology based on superlens for nano-scale lithography that may transform the next generation of nano-manufacturing, along with our first demonstration of plasmon lasers.
