摘要

在多层纳米谐振器中,包括由双各向同性材料或夹在介电层、epsiln -近零层或金属间隔层之间的超材料制成的主层,对反射和透射的电磁波进行了解析建模。基于电磁边界问题精确解的数值和图形分析,证实了将这种纳米谐振器用作超紧凑极化变换器的可能性。所提出的系统具有参数范围广和显著减小(亚波长)厚度的特点。间隔层可以对反射和透射辐射的手性和非互反效应进行修正、控制和放大。该概念可用于各种几何形状的介电层、epsilon-near-zero层、金属层、双各向同性层和超材料层,并用于开发新的超薄、大面积、相对易于制造的极化和其他纳米光子器件。

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