A simple horizontal dipole over ground can be used as a near-field probe for buried object detection if changes in the dipole impedance produced by the presence of the buried object can be correlated to the characteristics of the object. In this paper, the wideband variation in the input impedance of a horizontal dipole over ground caused by the presence of a nearby underground anomaly (tunnel) is...
In this paper, a technique is developed to compute values of the chirality, permittivity, and permeability of a dielectric reciprocal chiral slab from the knowledge of limited laboratory measurement information. The chirality parameter is a function of frequency and depth of the slab. The developed technique is based on the use of coupled differential equations for the Green functions associated with...
