Magnetic Field Above Stratified Earth in Magnetic Loop Through‐the‐Earth Wireless Communications
Lincan Yan, Miguel Reyes · Radio Science · 2022
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.
