已经开发出一种合成人工各向异性结构的有效分析方法。在设计频率下，它确保完美匹配和给定的相移。该结构可以由任意数量的电感性和电容性网格形成。该方法已应用于构造圆偏振片和扭曲偏振片。偏振器的几何参数以显式形式找到。已经导出了估计设备带宽的分析标准。研究了偏振器在频带上的性能。已经提出了一种圆偏振器，其由两个电感栅格的级联和两个电容栅格的级联组成。当需要非常高的轴比时可以使用偏光镜。保证0.99轴比10%以上的带宽。已经提出的测量结果证明了数学模型对于实际电感式和电容式屏幕的充分性。 >
An effective analytical method of synthesis of an artificial anisotropic structure has been developed. At a design frequency, it ensures perfect match and a phase shift given. The structure may be formed by arbitrary number of inductive and capacitive grids. The method has been applied to constructing circular polarizers and twist polarizers. The geometrical parameters of the polarizers were found in the explicit form. Analytical criteria for an estimate of the bandwidth of the devices have been derived. Performance of the polarizers over a frequency band was studied. A circular polarizer has been proposed which consists of both a cascade of two inductive grids and a cascade of two capacitive grids. The polarizer can be used when very high axial ratio is needed. It ensures more than 10% bandwidth for 0.99 axial ratio. Measurements have been presented that prove adequacy of the mathematical model for real inductive and capacitive screens. >
