Abstract
Evaluation of the very-low frequency, ultralow frequency, or extremely low frequency magnetic field (H-field) due to a buried or on-surface magnetic dipole or antenna is important for applications such as geophysical exploration and through-the-Earth (TTE) wireless communications. In this study, we develop an explicit form of magnetic field over multi-layer Earth medium (N > 3). The generalized solution is derived for operating frequency, mine depth, and Earth conductivity that would be typically related to TTE applications.
