| 摘 要： | 通过分析电磁波从管道开口耦合进入管道的绕射机理及场在腔体内的射线特征，将进入管道的绕射场展开为平面波谱，利用平面波在自由空间的传播特性分析了电磁波沿管道的传输和反射特征。通过算例验证了该算法的有效性。

| Abstract: | Through insight into the diffraction mechanism of electromagnetic wave coupling into the tube through its open end and the rays characters of field in the tube , the diffraction field in the tube is expanded into a set of plane waves, then the propagation and reflection features of the field inside tube can be analyzed easily just as if the plane wave propagate in free space. The effectiveness of the algorithm is demonstrated by numerical results. |
