摘要: 本文给出了金属细丝的电磁场衍射公式。对金属缝和互补屏窄条或细丝的线偏光衍射作了实验和理论研究,定量给出衍射法测量细金属丝直径的偏振效应。理论计算与测量结果基本一致。
Abstract: In this paper, formulas of electromagnetic field diffraction on a metal filament are given. We report the experimental and calculated results of diffraction of linear polarized light on a metal slit and its complemencary diffracting screen of filament. The polarization effect in diameter measuremenr of filament by diffraction method is presented quantitatively. Calculated results agree with experimental results.
