Abstract: During recent years, interest has been rising for applications of vector light beams toward magnetic field sensing. A series of experiments were performed to extract information about properties of static magnetic fields from absorption profiles of light passing through an atomic gas target. In this paper, we propose an extension to this method for oscillating magnetic fields. To investigate this scenario, we carried out theoretical analysis based on the time-dependent density matrix theory. We found that absorption profiles, even when averaged over typical observation times, are indeed sensitive to both strength and frequency of the time-dependent field, thus opening the prospect for a powerful diagnostic technique. To illustrate this sensitivity, we performed detailed calculations for the 5s2S1/2(F=1)-5p2P3/2(F=0) transition in rubidium atoms, subject to a superposition of an oscillating (test) and a static (reference) magnetic field.
