Meta Optics: Flat and Planar Lenses
The chapter discusses the concept of meta-optics and how they differ from conventional optical components. Meta-optics are completely flat and planar, unlike conventional lenses that have curvature. By changing the in-plane dimensions of nano structures, meta-optics can achieve similar effects as refractive lenses without the need for curvature.
