摘要： Systems and methods for RF magnetic-field vector detection based on spin rectification effects are described. In one embodiment, a method comprises sweeping a quasi-static external applied magnetic field at a h-vector detector, measuring voltages across terminals of the h-vector detector when the detector receives a microwave, varying the angle between the external applied static magnetic field and the RF current, determining an angular dependence of the measured voltages, and calculating a magnetic-field vector (h-vector) component of the microwave. In another embodiment, a method comprises providing an array of h-vector detectors, each element of the array being positioned at a different angle with respect to each other, subjecting the array to an external swept quasi-static magnetic field, measuring voltages across terminals of each element of the array when the array receives a microwave, associating each measured voltage with a respective angle, and calculating at least one h-vector component of the microwave.
