Abstract
This report describes numerical simulation results of wire detection using radio-frequency (RF) transmitter-receiver pairs at a single fixed frequency. The model is based on an analytical solution of Maxwell’s equations for a coil transmitter and receiver, and determines the response of a general wire detector as it is passed over a wire. Simulations are performed according to three steps: (1) based on the parameters of the transmitter dipole, calculate the current distribution within the wire to be detected, (2) integrate over the current distribution to determine the magnetic field at the location of the dipole receiver, and (3) repeat steps (1) and (2) for various locations along a traversal path. After discussing the theoretical basis and implementation of the model, general results are discussed. Finally, the model is applied to cases where the transmitter and receiver dipoles are fixed together and move as a complete unit.
