Low Loss Dielectric Materials and Their Applications

Abstract

In this chapter, we focus on discussing the dielectric materials with high refractive indices and low losses. Section 6.1 briefly introduces the research motivation and some key advantages of dielectric materials. Section 6.2 covers the fundamental electromagnetic properties of dielectric materials, elucidating the origin of low loss features and multipole Mie resonances. The commonly used fabrication techniques are also discussed. Sections 6.3 briefly reviews various applications of dielectric materials in manipulating electromagnetic waves, and explains how the unique physical properties of dielectric materials could benefit these applications. Finally, a short summary and future perspective are conceived in Section 6.4, including a brief comparison between dielectric and plasmonic metal materials.
