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. [ABSTRACT FROM AUTHOR]
