In this paper, the radiation characteristics and crosspolarization of microstrip antenna array on a grounded multilayer dielectric substrate using the spectral-domain method of moment is studied.
因而对多层介质微带阵列天线电磁特性的研究有着非常重要的意义。

Note that in light with orbital angular momentum, the direction of polarization (denoted by the direction of the arrow) does not change across the cross section.
值得注意的是，具有轨道角动量的光，偏振方向(用箭头方向表示)在截面内部发生变化。

The visible black polarizationcross like "X" was observed by the polarizing microscopy.
