Chirality in Electrodynamics: Modeling and Applications

  • Dwight L. Jaggard

Abstract

Recently, attention has been focused on the area of wave propagation, radiation and guidance in chiral media due to their diverse applications and availability. The role of chirality or handedness and its importance in a variety of fields such as geometry, chemistry, optics, particle physics and life sciences has been studied since the early part of nineteenth century. Chiral electrodynamics, or electromagnetic chirality, addresses the effects of handedness in electrodynamics, and these effects can be observed in chiral materials, which, in the optical regime are also known as optically active materials. Owing to the handed nature of their constituents, these materials themselves possess an intrinsic handedness.
