Abstract
Conventional optical systems (lenses, wave-plates and holograms) shape the wavefront of light within the range of an optical path that is much larger than the wavelength of light. The control of amplitude, phase and polarization of light depends on the dynamic optical path difference accumulated through the reflection, refraction and diffraction. Recently, planar ultrathin optical components have attracted tremendous attention by removing such traditional limitations. Among the competitive technologies, plasmonics is a promising field that enables the unique property of nanoscale confinement of electromagnetic fields. Plasmonic devices based on the manipulation of surface plasmons (SPs), a col-lective charge oscillation at metal/dielectric interfaces, have provided a confined environment for the full manipulation of light, and it is not surprising that this unique property of SPs has received considerable attentions. Meanwhile, engi-neered planar nanostructures, also named as metasurfaces, allow us to harness the light more smartly than any con-ventional ways. So far, a huge number of unprecedented optical components have been attained by the use of metasurfaces. As a result, plasmonic metasurfaces have become a whole new discipline within nanophotonics, because it can be perceived as a bridge connecting both electronics and optics, opening up opportunities for new and exciting applications.
