Abstract
A system and method for design and operation an acoustically driven ferromagnetic resonance (ADFMR) based sensor for measuring electromagnetic fields that includes: a power source providing an electrical signal to an ADFMR circuit, sensitive to electromagnetic fields, wherein the ADFMR circuit comprises an ADFMR device. The system detect and measure external electromagnetic (EM) fields by measuring a perturbation of the electrical signal through the ADFMR circuit due to the EM fields. The system and method may function to facilitate the design and operation of a chip-scale ADFMR device usable to measure EM fields.
