Abstract
Magneto-electric quasistatic (MEQS) field may be used to track positions of persons and/or objects inside metallic environments. A magneto-electric quasistatic field generator may generate a magneto-electric quasistatic field inside a metallic environment. A magneto-electric quasistatic field detector inside the metallic environment may detect the magneto-electric quasistatic field and generate output signals conveying characteristics of the magneto-electric quasistatic field. The relative position of the magneto-electric quasistatic field detector with respect to the magneto-electric quasistatic field generator may be determined based on the output signals. The position of the magneto-electric quasistatic field detector/generator and/or the position of a person/object carrying the magneto-electric quasistatic field detector/generator may be tracked using the relative position of the magneto-electric quasistatic field detector with respect to the magneto-electric quasistatic field generator.
