Transparent phase dielectric metasurfaces
This chapter provides an overview of transparent phase dielectric metasurfaces, a rapidly growing field that has potential to revolutionize optical materials and devices. The chapter starts with an introduction to simple harmonic oscillator and coupled oscillator models, which are useful for understanding the principles behind the design of some of these metasurfaces, while the surface equivalence principle, temporal coupled mode theory, and multipole decomposition methods are used to describe other transparent metasurfaces. The chapter covers several types of transparent phase dielectric metasurfaces, including Fano metasurfaces, Huygens metasurfaces, transverse Kerker metasurfaces, hybrid anapole metasurfaces, and Pancharatnam–Berry phase metasurfaces. Each section discusses the fundamental physics of the metasurface and its design principles, as well as recent advances and potential applications. This chapter aims to provide readers with a comprehensive understanding of the state-of-the-art in transparent phase dielectric metasurfaces and inspire further research in this exciting field.
