波导缝隙T型接头耦合特性的研究

Study of Coupling Properties for a Slot in Waveguide Tee Junction

本文研究通过任意取向缝隙耦合的 T 型接头的特性。根据电磁场理论建立严格的积分方程组,用伽略金法将积分方程组变换为矩阵方程,借助计算机求解散射场和耦合系数。这种方法计入了波导的实际壁厚,并适合于任意尺寸的主、辅波导,所得数值解精度高。

Coupling properties of a Tee junction through an arbitrarily oriented slot are studied.The problem may be described by integral equations,which are derived from electromagnetic theories. Galerkin's method is employed to transform the integral equations into a matrix equation,and scattering fields and coupling coefficicnts are obtained by means of a computer.The numerical re- sults can be achieved with high accuracy,since the thickness of waveguide walls is considered and the method is suitable for any sizes of feeding and coupling waveguides.
