A new diffraction field expression is proposed for a wedge with different face impedances. The modified theory of physical optics based diffraction coefficient is taken into account. The reflection coefficients are expressed in terms of the split functions that occur in the double integral solution of the resistive half-plane problem. The effects of wedge’s each faces are represented separately. The uniform field expression is obtained and compared with the literature for a right-angled impedance wedge numerically.

阻抗楔形波衍射

针对具有不同面阻抗的楔形体，提出了一种新的衍射场表达式。考虑了基于衍射的物理光学的改进理论。反射系数用在电阻半平面问题的双重积分解中出现的分裂函数表示。楔形每个面的效果分别表示。获得均匀的场表达式，并与文献中的直角阻抗楔形进行数值比较。
