Nanostructures have a different applications in sensors, spectroscopic and optoelectronic devices. Metamaterials have developed into one among the foremost focused research fields in nanooptics and nanomaterials and attract extensive research interests. this is often not only thanks to the rich physics during this quite materials, but also because they're closely associated with some new techniques within the control of terahertz radiation, solar energy management, optical cloaking, antenna systems, etc.
