Abstract
The exact operation mode of PHF H-plane waveguide circulator is given to be HE, where L=n+8x=1 n=0,1,2,.... and 8 can be determined numerically. A broadband 3-mm circulator operating in the lowest mode HE118 is reported for the first time. The center freguency of waveguide circulator agrees well with the resonance frequency of the dielectric ferrite resonator if no magnetic bias is applied(1). At r=R1 and r=R2 in Fig.1.
