Abstract
A ferrite modulator/switch is disclosed for use in a dielectric waveguide ansmission line. A ferrite guide section inserted in a dielectric transmission line is longitudinally magnetized to cause a 90.degree. rotation of a wave traveling through the guide thereby inhibiting further propagation and resulting in the scattering out of wave energy away from the dielectric line.
Claims5
A dielectric waveguide switch comprising:
- a ferrite waveguide section having an input end and an output end,
- a first dielectric waveguide means connected to said input end of said ferrite section for providing an input signal and a second dielectric waveguide means connected to said output end for receiving an output signal from said ferrite section, and
- means for selectively rotating the polarization of signals propagating through said ferrite waveguide section.
