Latching-type digital phase shifter employing toroids of gyromagnetic material

Claim 1

IN AN ELECTROMAGNETIC WAVE DEVICE EMPLOYING A MEMBER OF GYROMAGNETIC MATERIAL AND OPERATING TO HAVE THE MAGNETIZATION STATE OF SAID MEMBER SWITCHED BETWEEN TWO DIFFERENT MAGNETIZATION STATES TO EFFECT DIFFERENTIAL INTERACTION WITH LINEARLY POLARIZED ELECTROMAGNETIC WAVES WHEN IN THE TWO DIFFERENT MAGNETIZATION STATES, THE COMBINATION COMPRISING: ELECTROMAGNETIC WAVE PROPAGATING MEANS FOR PROPAGATING ELECTROMAGNETIC WAVES ALONG A GIVEN DIRECTION IN A MODE IN WHICH THE MAGNETIC FIELD COMPONENT IS LINEARLY POLARIZED IN A GIVEN REGION, A MEMBER OF GYROMAGNETIC MATERIAL THAT EXHIBITS GYROMAGNETIC EFFECTS TO SAID WAVES, SAID MEMBER BEING POSITIONED IN SAID GIVEN REGION SUCH THAT AN AXIS OF SYMMETRY OF SAID MEMBER IS TRANSVERSE TO SAID GIVEN DIRECTION AND SUBSTANTIALLY COINCIDENT WITH THE AXIS OF AN APERTURE IN SAID MEMBER, FIRST MEANS FOR MAGNETIZING SAID MEMBER IN A FIRST DIRECTION AROUND SAID AXIS, WHEREBY SAID MEMBER PRESENTS A FIRST VALUE OF PERMEABILITY TO SAID WAVES, AND SECOND MEANS FOR MAGNETIZING SAID MEMBER IN A SECOND DIRECTION ORTHOGONAL TO SAID FIRST DIRECTION SO THAT SAID MEMBER PRESENTS A SECOND VALUE OF PERMEABILITY TO SAID WAVES, SAID FIRST AND SECOND MEANS BEING ACTUATED ALTERNATELY TO SWITCH THE MAGNETIZATION OF SAID MEMBER BETWEEN SAID FIRST AND SECOND DIRECTIONS.
