Experimental Demonstration of Complex Image Theory for Vertical Magnetic Dipoles with Applications to Remote Sensing and Position Tracking-Image

The TX was moved along the x-axis in over the grassy field from x = 3 to 25 m while the RX stayed in a fixed location above the origin at a height of 74 cm.

Position and orientation tracking in the magnetoquasistatic region of an electrically small transmitting loop antenna make use of complex image theory (CIT), which is an approximate algebraic model of the fields above a lossy dielectric, semi-in finite half-space. Experimental demonstrations of CIT from a transmitting loop that approximates a horizontal magnetic dipole (HMD) have been reported previously. This work reports the first experimental demonstration of CIT from a vertical magnetic dipole (VMD) in remote sensing and position tracking applications.
