Reflection and transmission of nanoresonators including bi-isotropic and metamaterial layers: opportunities to control and amplify chiral and nonreciprocal effects for nanophotonics applications

Electromagnetic waves reflected from and transmitted through the multilayer nanoresonators including main layer made of a bi-isotropic material or metamaterial sandwiched between dielectric, epsilon-near-zero metallic spacer layers have been analytically modeled. The numerical graphical analysis, based on exact solution electromagnetic boundary problem, confirms opportunities to use such as utracompact polarization converters. proposed systems are characterized by wide ranges parameters significantly reduced (subwavelength) thicknesses. can provide modification, control, amplification chiral nonreciprocal effects for radiation. concept be realized various geometries epsilon-near-zero, metallic, bi-isotropic, used develop new ultrathin, large area, relatively easy-to-manufacture other devices nanophotonics.
