摘　　要：以耦合波理论为基础,提出了基于最速下降原理的过模波导器件迭代设计方法,并提出了结构控制技术和多频设计技术来满足结构特性和频响特性需求。该方法能够对过模波导器件进行统一有效设计。设计了中心频率为35 GHz、半径为13.6 mm的TE01-TE11模式变换器,采用多频设计技术,相对带宽可达到13.6%,相比于单频设计方法,带宽增加了2.3倍。An iterative method based on coupled mode theory is proposed in this paper,also structural controlling and multifrequency design techniques are proposed to satisfy the structural property and frequency response property requirements.The iteration method can be used to design many kinds of waveguide components.A TE01-TE11 mode converter is designed,the working frequency of which is 35 GHz,and the radius is 13.6 mm.The multi-frequency technique is utilized.The bandwidth reaches 13.6%,which is the 2.3 times of conventional method.
