The scattering of a Gaussian beam by a resistive half-screen is investigated. Far-field approximation is used in evaluation of geometrical optics and diffracted waves. The uniform expression of the diffracted waves by the resistive half-plane, which was found with the Sommerfeld-Maliuzhinets method, is obtained. The scattered fields for the case of the beam incidence are evaluated with the technique of a complex point source. The resultant wave expressions are examined numerically.
研究了高斯光束被电阻性半屏的散射。在几何光学和衍射波的评估中采用了远场近似。利用索末菲 - 马柳日涅茨方法得到了电阻性半平面衍射波的统一表达式。采用复点源技术评估了光束入射情况下的散射场。对所得的波表达式进行了数值检验。
