摘　　要：波导位移引起的反射，已有公式可查，但当位移值较大时，现有方法的计算值误差较大。本文验证了采用加权盖根堡（Ｇｅｇｅｎｂｅｕｅｒ）多项式来描述波导位移平面内的场时所给出的近似公式，它可解决波导位移值一直到２５％波导尺寸时反射系数的计算。It is available to calculate the reflection due to the displaced rectangular waveguides with the existing formula￣[3]. But the error between the calculation from this formula and the exporiment is too big,when the displacement is little larger. In this paper,we use an approximate formula in which the fields in the displaced ptane of the wavegulue are given by the weighted Gegenbauer’s polynomials.It is found that the calculation with this formula is valid when the displacement of the waveguide is increased up to 25%of the dimensions of the waveguide by our experiments.
