【摘要】 根据电磁波在边界上传播的特性，对填充无耗介质层的理想极化层金属搬进行了研究，对极化栅间的多次反射和介质层引入的多重反射，利用集合射线理论，避免了繁琐的数值积分，导出宽带斜45°极化器电性能计算公式；最后将相应的计算结果与工程测量结果进行比较，相当吻合。更多还原

【Abstract】 According to the propagation characteristics of the electromagnetic wave along theboundary,the ideal metal-grid polarization layer filled with lossless medium is analyzed. In view ofthe several reflections between the polarization layers and the multi - reflection induced by the medium layers,the electrical characteristics calculation equation of the broadband 45° oblique polarizeris proposed by utilizing the set ray theory,so the complicated numerical integration is avoided. It isshown that the corresponding calculation values and the engineering measurement results are ingood agreements.更多还原
