Polarization conversion of electromagnetic waves transmitted through multilayer nanoresonators, including a main homogeneous layer made of a transparent uniaxial dielectric sandwiched between epsilon-near-zero and metallic spacer layers, has been analytically modeled. The numerical analysis, based on exact solutions of electromagnetic boundary problems, confirms opportunities to use such multilayers as utracompact polarization converters (in particular, zero-order quarter and half waveplates) of a new type. The proposed systems are characterized by much wider ranges of parameters and significantly reduced (nanometric) thicknesses in comparison with the conventional waveplates. The operation regimes, resulting from the features of amplification of proper wave phase differences under multibeam interference conditions, are considered. The concept can be realized for both metamaterial-dielectric-metamaterial and metal-dielectric-metal structures and used for the development of ultrathin, large area, and simple in fabrication polarization devices for photonic applications.

已经对通过多层纳米谐振器传输的电磁波的极化转换进行了建模，该多层纳米谐振器包括一个主要的均质层，该均质层由夹在epsilon-near-zero-零和金属间隔层之间的透明单轴电介质制成。基于对电磁边界问题的精确解决方案进行的数值分析，证实了使用此类多层作为新型超紧凑型偏振转换器（特别是零阶四分之一和半波片）的机会。与常规波片相比，所提出的系统的特征在于参数范围更广，厚度（纳米）显着减小。考虑了由于在多光束干扰条件下适当波相位差的放大特征而导致的工作方式。
