Abstract

A waveguide circulator includes a resonator body which is separated from a waveguide side by a dielectric spacer disc. The spacer disc has an interface turned toward the waveguide side in which defined electromagnetic boundary conditions are to prevail. The thickness of the spacer disc and the dielectric constant of the disc material are matched so that the disc thickness equals a quarter wavelength, referred to a wave propagating in the disc perpendicular to the waveguide side.
