Abstract : A switchable dielectric waveguide circulator is provided for millimeter wave frequency applications comprising a ferrite right prism having two polygonal prism bases and at least three lateral prism faces. A control wire is threaded through a number of bores formed in the prism in a plane between the bases. Each of the bores is spaced a distance from a different one of the apices of the prism so that a control current passing through the control wire creates a circular magnetic field about each bore which combine to form a resultant magnetic field between the prism bases which cause the prism faces to act as circulator ports. The rotational direction of circulator coupling action is reversed by reversing the direction of the control current. Both Y-junction and T-junction circulator configurations are shown. Patent Application.
