Near-field imaging of buried conductors using transient EM signal transfer

Abstract

Abstract A novel time-domain electromagnetic (TDEM) technique for reliable detection and imaging of visually obscured buried conductors using only two rapidly acquired measurements via a simple and cost-effective antenna system is presented. This non-invasive method exploits transient electromagnetic (EM) interactions to detect contrasts in electrical conductivity between targets and the surrounding medium. This approach provides a practical and flexible alternative to conventional subsurface sensing technologies. The presented results show that the proposed technique yields accurate and repeatable outcomes across various shapes of buried targets.
