Abstract:

A tetrahedral junction waveguide switch is provided having two axially juxtaposed sections of hollow rectangular waveguide which are mutually cross-polarized by being rotated 90 degress with respect to each other. A rod of a ferrite material having gyromagnetic properties is axially disposed within the juxtaposed ends of the waveguide sections and is selectively axially magnetized to control transmission of RF electromagnetic wave energy through the sections. A permanent magent structure having a unique cladding arrangement which minimizes flux leakage and produces a magnet of high coercive force is employed to produce a undirectional magnetic bias field along the longitudinal axis of the rod to keep the switch in a low loss transmission state by virture of Reggia-Spencer effect signal rotation. A selectively operable helical coil is utilized to produce another axial magnetic field which nullifies the bias magnetic field when it is desired to place the switch in a high loss or cut-off transmission state.
