| 摘 要： | 利用任意闭合曲面对曲面外任一点所张立体角为零的特点将椭圆形波导管中对波导管侧面的积分转变为对椭圆形波导管横截面的积分 ,在轴向采用线性插值函数的条件下对椭圆形波导管横截面的积分简化为一维积分。 |

| Abstract: | Using the solid angle that a closed surface opens to an outer point of that is zero,the integration for lateral surface of elliptic waveguide has been changed into the integration for the cross section of the elliptic waveguide Therefore,under the assumption that the interpolation functions between nodal points are linear in direction of axis,the integration for the cross section of the elliptic waveguide has been simplified into one dimensional integration |
| Keywords: | solid angle integral equation elliptic waveguide |
