Chiral devices - an overview of canonical problems

Abstract

Many canonical problems whose solution may eventually result in useful chiral devices are reviewed in this paper. These devices could be broadly divided into two main categories: those which are based on wave propagation in layered chiral structures and those which are based on wave propagation along waveguides containing or composed of chiral materials. To these should be added chirostrip antennas, chirolenses and chirodomes. Potential applications are proposed in most of the canonical examples described. They encompass a wide range of frequencies, from millimeter waves to the optical spectrum.
