Abstract
Electromagnetic and optical shields, controllers, and reflectors comprising chiral materials. Electromagnetic and optical controllers and layers provided in accordance with this invention comprise chiral materials wherein reflection, scattering, absorption and shielding properties can be tailored over specified frequency regime. Layered structures have a variety of potential applications in radar cross section management, radar absorbers for low observables and other applications, radomes, antennae, and radio wave, microwave and millimeter wave chambers. Likewise, these structures have many applications to electronic devices, integrated optics, and optical components and systems, as well as in their radio wave, microwave, and millimeter wave counterparts.
