Abstract
A system for an acoustically driven ferromagnetic resonance (ADFMR) based sensor. The system may include a power source, that provides an electrical signal to power the system, at least one circuit comprising a set of ADFMR circuits, sensitive to external electromagnetic fields, a power splitter, a power combiner and a detector circuit. The system functions to detect and measure external electromagnetic (EM) fields by measuring a perturbation of the electrical signal through the ADFMR circuits due to the EM fields.
