Abstract : The patent describes an improvement over the existing art in microwave phase shifters of the nonreciprocal class. The invention employs a toroid of ferromagnetic material which can be magnetized in at least two of its remanent states. Higher interaction with microwave energy is obtained when a periodic disturbance is introduced into the transmission line which disturbance is introduced into the transmission line which slows the propagating wave and provides a higher degree of circular polarization in the active of the toroid. Periodic perturbation of the electromagnetic field is accomplished by spacing partitions across the waveguide which are loaded with ferrite toroids. The dimensional spacing of the partitions is on the order of a fraction of a free-space wavelength.
