The radiation losses of the HE(11) mode of a fiber with sinusoidal radius fluctuations are calculated in the weak guidance approximation. The loss formula is derived by means of the volume current method and also by using coupled mode theory. The result presented here extends earlier results to the case of radiation escaping nearly perpendicular to the fiber axis.
在弱导近似下，计算了具有正弦半径波动的光纤HE(11)模的辐射损耗。损耗公式通过体电流法以及耦合模理论推导得出。这里给出的结果将早期结果扩展到了辐射几乎垂直于光纤轴逸出的情况。
