Abstract This report discusses the magnetic modeling results of a proof of concept system for 1/f noise mitigation in "large" sensors. The 1/f noise reduction is achieved by rotating flux concentrators that shift the operating frequency of the sensor to higher frequencies where 1/f noise is lower. The goal is to design systems with magnetic flux concentrators that maximize the enhancement of the field and the percentage modulation of the field but minimize size. These issues in execution and necessary tradeoffs in performance are discussed, and magnetic modeling is presented, showing a clear road map to increased performance from the viewpoint of field enhancement and modulation.
