The scope of this book is to introduce the optical fundamentals and basic optical design methods of a m etalens, where light propagation can be modelled by simple, and yet useful basic optics (e.g., the refraction law of metasurfaces, the wave front propagation, the metasurface phase profile, meta-atoms, etc.). 410 0$aIOP Series in Emerging Technologies in Optics and Photonics Series 606 $aMetasurfaces$7Generated by AI 606 $aOptics$7Generated by AI 615 0$aMetasurfaces 615 0$aOptics 676 $a681.423 700 $aMoreno$b Ivan$01847571 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 912 $a9911026042403321 996 $aIntroduction to Metalens Optics$94433410 997 $aUNINA
