Abstract
Quasistatic through-the-wall non-line-of-sight coupling between a mobile transmitting device located within a metallic enclosure, and a fixed receiving device located outside the enclosure, enables positioning of the transmitting device through the wall of the enclosure and in non-line-of-sight environments. The coupling of the magnetic and electric quasistatic fields occurs through a small aperture in the metallic enclosure, such as the gap normally present in the hatch of industrial metallic enclosures.
