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.
