title: Reconfigurable broadband infrared circularly polarizing reflectors based on phase changing birefringent metasurfaces.
abstract: This paper discusses a theoretical approach towards synthesizing broadband circularly polarizing reflectors. The broadband polarizing reflectors consist of birefringent metallo-dielectric metasurfaces which are described by the Jones matrices and verified via full-wave simulations. Specifically, full-wave simulations for candidate designs are presented that target operation in the near infrared band. In addition, reconfigurability is introduced and demonstrated for candidate designs at the long wave infrared band through the inclusion of a bistable phase change chalcogenide glass substrate.
