摘　　要：两个正交矩形波导公共宽边上偏离中心线的耦合斜槽称为复合耦合槽。考虑波导壁的厚度，根据等效原理和缝隙口面切向磁场的连续条件建立一对耦合积分方程，利用矩量法进行求解，给出复合耦合槽的谐振长度、散射参量随缝隙的倾角。A compound coupling siot is defined as the centered-inclined coupling slot which is offset from the longitudinal line of the two waveguides in the two crossed rectangular waveguides. According to equivalen principle and the continuity of tangential magnetic fields on the upper and lower surfaces. a pair of coupling integral equations is established,taking the waveguide wall thickness into account. The equations can be solved by the Moment Methods,then,the resonant length of the compound coupling slot, the scattering parameters for the tilt angle Of the slot and the slot offset, and the impedance parameters of the equivalent type T network are given.
