Polarization effects on two-dimensional active imaging of conducting objects buried in a dielectric half-space

Abstract

The polarization effects on two-dimensional quasi-exact active imaging for conducting objects buried in a dielectric half-space are investigated for plane wave incidence. It was found from numerical simulations that for TM (transverse magnetic) wave incidence the upper contour of the buried object is well reconstructed, but the lower side could not be reconstructed, while for TE (transverse electric) wave incidence both sides can be reconstructed for thin objects.<>
