矩形波导任意弯角的对称切角的矩量解

Moment Solution for Rectangular Waveguide Arbitrary Angle Bends with a Corner Cut Symmetrically

本文利用奇、偶模激励方法对对称切角的矩形波导的任意弯角进行了研究。用矩量法求解矩形波导中等效电壁和磁壁上的电磁场积分方程,分别求得奇、偶模激励时的反射系数,从而得到弯角的散射参数。计算结果与实验值吻合较好。

E-plane and H-plane rectangular waveguide bends of arbitrary angle with a corner cut symmetrically are investigated in this paper in terms of the equivalence of evenand odd-mode excitations. The electric and magnetic field integral equations on the equivalent electric and magnetic wails in the rectangular waveguide are solved by the method of moment. The reflection coefficients for evenand odd-mode excitations are obtained respectively, from which the scattering parameters are calculated. The results show good agreement with those obtained by the experiments.
