Dielectric waveguide circulator

摘要

Millimeter wave circulators are disclosed for use with millimeter wavelength dielectric waveguides. The structure comprises a prism of magnetized ferrimagnetic material with the waveguide ends bonded to the lateral faces of the prism. The waveguide ends and the lateral faces are congruent rectangles. The prisms may have triangular bases in which case a Y-junction circulator results, or square bases with waveguide ends attached to three out of four of the lateral faces thereof, whereby a T-junction circulator results.
