摘要： The present disclosure relates to a depolarizer based on a metamaterial, which comprises a plurality of sheet layers parallel with each other. Each of the sheet layers has a sheet substrate and a plurality of man-made microstructures attached on the sheet substrate. The sheet substrate is divided into a plurality of identical unit bodies. Each of the unit bodies and one of the man-made microstructures that is attached thereon form a cell that has an anisotropic electromagnetic property. Each of the sheet layers has at least two cells whose optical axes are unparallel with each other. According to the depolarizer based on a metamaterial of the present disclosure, at least two cells whose optical axes are unparallel with each other are disposed in each of the metalmaterial sheet layers. Therefore, when an electromagnetic wave having a uniform polarization property propagates through the metamaterial, at least part of the electromagnetic wave will be changed in polarization property, thus achieving the purpose of depolarization. Moreover, as compared to the prior art, the depolarizer of the present disclosure features a simple structure and is easy to be implemented.
摘要翻译： 本公开涉及一种基于超材料的去极化器，其包括彼此平行的多个片层。 每个片层具有片状基材和附着在片状基材上的多个人造微结构。 片状基板被分成多个相同的单位体。 每个单元体和附着在其上的人造微结构之一形成具有各向异性电磁特性的单元。 每个片层具有至少两个细胞，其光轴彼此不平行。 根据本公开的超材料的消偏振器，至少两个光学轴彼此不平行的单元被布置在每个金属材料片层中。 因此，当具有均匀偏振特性的电磁波通过超材料传播时，电磁波的至少一部分将会发生偏振性变化，从而达到去极化的目的。 此外，与现有技术相比，本公开的去极化器具有简单的结构并且易于实现。
