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.
