This book provides an overview of the basic optics of the metalens, providing an introduction for students, scientists and engineers. The scope of this book is to introduce the optical fundamentals and basic optical design methods of a metalens, 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.). The book provides the historical background about metasurfaces and the metalens, reviews the basics of metalens optics, the design and analysis of meta-atoms, optical design of metalens, and provides several of the main optical designs of metalens systems. This basic introduction to metalens optics may provide a practical starting point for the study of the next generation of flat lenses based in nanotechnology.
