摘要 本文使用时域有限差分法 (FDTD法 )对由两根正交矩形波导构成的复合缝耦合器进行了严格分析 ,得出在不同偏置、倾斜角度和谐振频率下耦合缝隙的谐振长度和散射参量特性 ;并对带有短路器的复合缝波导耦合器系统进行了分析 。 A rigorous analysis of a compound slot coupler between two crossed rectangular waveguides using FDTD method is presented in this paper. Coupling slot characteristics are obtained, including the resonant length and scattering parameters in different offsets, tilt angles and frequencies. We also analyzed a kind of compound slot coupler system with short circuit port and obtained properties of S 31 when the short circuit terminal moved along the axis of main waveguide.
