Prerequisites
Basic knowledge of electromagnetism and mechanical waves.Description
Metamaterials that mimic the order in matters have opened an exciting gateway to reach unprecedented physical properties and functionality unattainable from naturally existing materials. The "atoms" and "molecules" in metamaterials can be tailored in shape and size, the lattice constant and inter-atomic interaction can be precisely tuned, and "defects" can be designed and placed at desired locations. Recent studies have demonstrated engineering metamaterials with unprecedented characteristics such as left-handedness with simultaneous negative permittivity and permeability, negative lens that focus electromagnetic waves far below the diffraction limit, artificial magnetism from nonmagnetic materials, and invisibility cloaking of electromagnetic energy.
This introductory course is designed to cover the technology fundamentals of the optical and mechanical metamaterials, micro-/nano-fabrication methodologies, and prospective applications. Specific topics include sub-wavelength waveguiding and focusing, super-resolution imaging and nano-lithography beyond the diffraction limit of the light, negative refraction, and invisibility cloaking. Plasmonic metamaterials, bio- sensing, enhanced Raman scattering, extraordinary transmission, Graphene Plasmonics, light-trapping for solar cell will also be discussed.
