1、With plasmonic metamaterials, we can manipulate the light based on plasmonic resonance effects of metallic nanostructures, realizing many novel interesting applications, such magnetic plasmon, chirality, nanolasers etc.

2、With transformation optical metamaterials, we manipulate the light by mimicking the curved space-time in general relativity, realizing many novel interesting applications, such black hole, light trapping, nanofocusing etc. 

3、Optical metamaterials has strong local field enhancement and resonance absorption, which can be applied to optical force, photothermal effects, optofluidics etc.
