Abstract

A characteristic of the E-plane circulator is that it displays two neighbouring solutions for the first and second circulation conditions. The so-called small gap E-plane circulator was dealt with in the literature. This paper is concerned with the large gap geometry. It outlines a simple eigenvalue subroutine for the design of either arrangement, and includes some experimental data in WR75 waveguide for the degree-one large gap geometry. Good agreement was found between numerical simulations and experiments. High peak power analysis showed a significant improvement for large gap E-plane geometry, in comparison to the small gap E-plane as well as the H-plane junction circulator.

大间隙e平面Omori环行器：一、二次循环条件

e -平面环行器的一个特点是它在第一和第二循环条件下显示两个相邻的解。在文献中讨论了所谓的小间隙e平面环行器。本文研究的是大间隙几何。它概述了一个简单的特征值子程序来设计这两种排列，并包括一些实验数据在WR75波导的一级大间隙几何。数值模拟与实验结果吻合较好。峰值功率分析表明，与小间隙e平面和h平面结环行器相比，大间隙e平面几何形状有显著改善。
