The scattering process of electromagnetic plane waves by a resistive half-screen is investigated for oblique incidence. First of all, it is shown that the existing solution in the literature is not correct, because the problem was solved by considering the normal components of the electromagnetic field, in terms of which the boundary conditions cannot be expressed. Instead of these, the components of the electric field, which is parallel to the edge discontinuity, are taken into account. The diffracted fields are obtained with the aid of the method of transition boundary. The uniform field expressions are obtained by using the Fresnel function. The behaviors of the total field and its subcomponents are analyzed numerically.

电阻半屏对平面电磁波的衍射,以产生偏斜入射。

研究了电阻性半屏对电磁平面波的散射过程的斜入射。首先,表明现有文献中的解决方案是不正确的,因为该问题是通过考虑电磁场的正态分量解决的,而正态分量无法表达边界条件。代替这些,考虑平行于边缘不连续性的电场的分量。借助于过渡边界的方法获得衍射场。统一字段表达式是通过使用菲涅耳函数获得的。对整个场及其子组件的行为进行了数值分析。
