从截止波导和介质波导两个方面分析了截止波导管穿光纤对屏蔽室的影响,认为引起屏蔽效能降低的原因是波导管端口辐射和端口边缘绕射,并给出了实际应用中的改善方法。
From the cutoff waveguide and the dielectric waveguide, the effect of the cut-off waveguide fiber on the shielding chamber is analyzed. The reasons for the reduction of the shielding effectiveness are the waveguide port radiation and the port edge diffraction, and the improvement methods in practice are given .
