Transient electromagnetic fields of a finite circular loop in the presence of a conducting half‐space

摘要

A previous solution for a pulse‐excited dipole is extended to allow for the finite size of the buried source loop. Numerical results for the above surface fields are presented. We also consider the situation when the finite source loop is located on the surface and the observer is buried. It is suggested that the waveform of the received pulse signals can be used for direction‐finding and source location.
