Abstract:
A resonator structure comprising:a first resonator comprising a first resonator loop formed by a hollow channel with conductive walls to confine a first high frequency magnetic field;a second resonator comprising a second resonator loop formed by a hollow channel with conductive walls to confine a second high frequency magnetic field, wherein flux lines of said first magnetic field are substantially orthogonal to flux lines of said second magnetic field, and wherein the first resonator loop and the second resonator loop intersect so that the first and second resonator loops are substantially shielded to prevent coupling of said first and second magnetic fields from the first and second resonator loops; andmeans for adjusting the orthogonality of the magnetic fields within said first and second resonator loops by adjustably rotating said second resonator with respect to said first resonator about either of two orthogonal axes passing through the intersection of said first and second resonators.
