摘　　要：光介质波导中的多模干涉效应和自成像现象已经被成功地应用于设计结构简单、易制造的光功率分配器。在本文中,我们展示了微波频段下,金属矩形波导中的多模干涉效应和自成像现象,并设计了一款工作在40GHz的1×2功率分配器。仿真实验结果表明,使用多模干涉效应设计的金属波导的微波功率分配器具有良好的能量均衡特性。Multimode interference effects and self-imaging phenomena in optical dielectric waveguides have been successfully applied to design simple and easily fabricated optical power dividers.In this paper,we demonstrate multimode interference and self-imaging in metallic rectangular waveguides at microwave frequency,and design a 1×2 power divider operating at 40GHz.The simulation results show that the microwave power divider based on the multi-mode interference effect has good energy balance characteristics.
