【摘要】 本文提出了计算圆锥喇叭变张角截面波型转换和反射的近似计算方法。它比目前不计反射波型的方法较为精确。当输入只含低次模时,各系数收敛极快,占用计算机时间很短,故可在圆锥多模喇叭设计中使用。更多还原

【Abstract】 The formulas for calculating transmission and reflection modes at the junction withchange in aperture angle are derived. Some approximations have been taken in order tomake the formulas suitable for engineering purposes. This new method is more accuratethan the one now used which neglects all the reflection modes. The coefficients convergerapidly when the input contains only lower modes. Therefore the time on computer isvery short and these formulas can be used in the design of multimode conical horn.更多还原
