On the use of evanescent electromagnetic waves in the detection and identification of objects buried in lossy soil.

On the use of evanescent electromagnetic waves in the detection and identification of objects buried in lossy soil.

In some electromagnetic (EM) systems proposed for the detection of buried objects, such as landmines, the transducers (antennas) are located very close to the surface of the Earth. The coupling of energy into the Earth is then by the near field of the transducers, or, more precisely, by evanescent w...
