Claim 1
Independent Claim
105 words
A GYROMAGNETIC RESONANCE APPARATUS COMPRISING: A CAVITY RESONATOR STRUCTURE FOR ACCOMMODATING SIMULTANEOUSLY THEREIN TWO GYROMAGNETIC SAMPLES POSITIONED INA POLARIZING MAGNETIC FIELD; MEANS FOR EXCITING SAID CAVITY STRUCTURE WITH ELECTROMAGNETIC ENERGY AT THE RESONANT FREQUENCY THEREOF, FOR SIMULTANEOUS IRRADIATION OF SAID SAMPLES AT SAID FREQUENCY WHEREBY THE MAGNETIC FIELD COMPONENST OF SAID ENERGY INDUCES GYROMAGNETIC RES-ONANCE IN SAID SAMPLES; MEANS FOR SEPARATELY AND SIMULTANEOUSLY MODULATING THE POLARIZING FIELD AT EACH SAMPLE AT RESPECTIVE DIFFERENT FREQUENCIES; AND MEANS FOR SIMULTANEOUSLY AND SEPARATELY DETECTING A MODULATION IN THE MICROWAVE IMPEDANCE OF SAID CAVITY RESONATOR STRUCTURE AT EACH OF THE MODULATION FREQUENCIES DUE TO GYROMAGNETIC RESONANCE IN SAID SAMPLES.
