| 摘 要： | 采用基于场匹配理论的数值计算和仿真技术对中心频率为0.225 THz的两路波导功率合成器的场分布特性及合成效率进行了研究。数值计算结果表明:随着两路输入波相位差的增大，合成波束的峰值场的幅值逐步减小；增加输入波导间隔板厚度，合成波束峰值场的位置逐步远离输入端口，使合成波导的长度增加；仿真和数值计算得到了基于一致的结果。仿真结果表明:当两路输入信号的相位差小于35°时，合成效率大于90%，带宽为10.000 GHz。

| Abstract: | A rectangular waveguide two-way power combiner with the center frequency of 0.225 THz is designed.The distribution of electric field and the efficiency of the combiner are investigated by numerical calculation and simulation.The numerical calculation shows that the combined peak electric field decreases as the phase difference of the two input waves increases.The position of the combined peak electric field moves away from the input port with the increase of the space between the two input waveguides.The re... |
