Non-reciprocal tm mode transducer

Claim 1

AN ELECTROMAGNETIC WAVE TRANSDUCER FOR NON-RECIPROCALLY PROPAGATING ELECTROMAGNETIC WAVES WITHIN A GIVEN FREQUENCY RANGE IN A TRANSVERSE MAGNETIC MODE, SAID TRANSDUCER INCLUDING A DIELECTRIC WAVE PROPAGATING MEDIUM EXTENDING LONGITUDINALLY AND COMPRISING A PLURALITY OF MUTUALLY TRANSVERSE REGIONS HAVING SUBSTANTIALLY DIFFERENT DIELECTRIC CONSTANTS, MEANS FOR IMPRESSING SAID ELECTROMAGNETIC WAVES IN SAID TRANSVERSE MAGNETIC MODE ONTO SAID PROPAGATING MEDIUM, AT LEAST TWO OF SAID PLURALITY OF REGIONS BEING SEPARATED BY A BOUNDARY THAT EXTENDS TRANSVERSELY TO MAGNETIC FIELD COMPONENTS OF SAID SOLELY TRANSVERSE MAGNETIC MODE, WHEREBY SAID WAVES PROPAGATE WITH DIFFERENT PHASE VELOCITIES IN SAID TRANSVERSE REGIONS TO PRODUCE A CIRCULARLY POLARIZED MAGNETIC FIELD COMPONENT IN SAID WAVES, ONE OF SAID TRANSVERSE REGIONS BEING COMPRISED OF A MAGNETIZED MATERIAL THAT EXHIBITS GYROMAGNETIC EFFECTS TO SAID WAVES IN SAID GIVEN FREQUENCY RANGE, SAID GYROMAGNETIC MATERIAL BEING MAGNETIZED IN A DIRECTION TRANSVERSE TO SAID CIRCULARLY POLARIZED MAGNETIC FIELD COMPONENT AND TRANSVERSE TO SAID WAVE GUIDING MEDIUM.
