论文摘要
提出了一种简单但有效的方法，用于合成传输型宽带极化转换器。所提出的配置包括多层元面积，包括谐振粒子，这些粒子逐层逐步旋转。颗粒的进行性旋转允许在大频带上进行极化转换。偏振结构是通过传输线模型方法有效设计和优化的，该方法处理各向异性阻抗层和介电的级联。将基于逐渐旋转的偶极谐振器的优化的8层设计作为概念证明。一旦对结构进行了优化，将通过有效传输线模型获得的结果与全波模拟进行了比较。宽带极化转换器的原型已经制造和测量。
A simple but efficient approach for the synthesis of transmission-type wideband polarization converters is presented. The proposed configuration comprises multilayer metasurfaces including resonant particles which are progressively rotated layer by layer. The progressive rotation of the particles allows for a polarization conversion over a large frequency band. The polarizing structure is efficiently designed and optimized through a transmission line model approach handling the cascade of anisotropic impedance layers and dielectrics. An optimized 8-layers design based on gradually rotated dipole resonators is presented as a proof of concept. The results obtained through the efficient transmission line model are compared with full-wave simulations once that the structure was optimized showing satisfactory agreement. A prototype of the wideband polarization converter has been fabricated and measured.
