Constant phase shift faraday rotator

Claim 1

A FARADAY ROTATION DEVICE COMPRISING MEANS FOR DIRECTING THE PROPAGATION OF LINEARLY POLARIZED MICROWAVE ENERGY UNDER VARIOUS DEGREES OF ROTATION ALONG A PRESCRIBED AXIS, FIRST AND SECOND SUBSTANTIALLY IDENTICAL GYROMAGNETIC MEDIA MUTUALLY DISPLACED ALONG SAID AXIS, EACH OF SAID MEDIA HAVING DISCRETE VALUES OF PERMEABILITY AND PERMITTIVITY, ONE OF SAID VALUES IN EACH MEDIUM HAVING ORTHOGONAL TENSOR COMPONENTS REPRESENTED BY A SKEWSYMMETRIC MATRIX WHEREIN THE VELOCITIES OF PROPAGATION OF OPPOSITELY ROTATING CIRCULARLY POLIARIZED COMPONENTS OF MICROWAVE ENERGY PROPAGATING THROUGH SAID MEDIUM CHANGE WITH RESPECT TO AN AXIAL MAGNETIC BIAS ACCORDING TO PREDETERMINED FUNCTIONS DEPENDING UPON THEIR SENSE OF ROTATION, MEANS FOR MAINTAINING AN OPPOSITELY DIRECTED AXIAL MAGNETIC BIAS IN EACH OF SAID MEDIA, SAID BIASING MEANS BEING ADJUSTED TO BIAS EACH GYROMAGNETIC MEDIUM TO A LEVEL WHERE THE RATES OF CHANGE OF PHASE SHIFT WITH CHANGE IN BIAS ARE SUBSTANTIALLY EQUAL AND OPPOSITE, AND INTERDEPENDENT CURRENT ADJUSTING MEANS FOR INCREASING THE MAGNETIC BIAS IN ONE MEDIUM WHILE SIMULTANEOUSLY DECREASING THE MAGNETIC BIAS IN THE OTHER MEDIUM BY THE SAME ABSOLUTE MAGNITUDE.
