Modeling of a Magnetic Flux Concentrator

Abstract

We performed magnetic modeling of a new and novel magnetic sensor from Visidyne Corp. The sensor is a high sensitivity vector field magnetometer. Such sensors have considerable potential for use as unattended ground sensors (UGS), alone or networked with other types of sensors, and to detect underground facilities. At frequencies over 10 Hz, the Visidy sensitivity of 5pT square root Hz makes the sensor promising for UGS type applications. Below this frequency the sensor is limited by geomagnetic noise. Still higher sensitivity is desired for the detection of underground facilities.
