Subsurface sensing in dielectric and conductive media

In the present work the new results of experimental investigations on through-wall and wall imaging(TWWI) using microwave tomography technique are submitted. Tomographic algorithm is employed for cross section imaging of dielectric and metal objects on the other side of concrete wall and within the concrete block. The present work contains experimental results obtained by eddy current near field microscopy of metal structures. The described experimental setup has been used for the detection of suspicious materials in envelops.
