Abstract

Metal detection systems currently available to the general public ordinarily verify

the presence of conductive material, not the shape. Shape detection is important for

discrimination between dangerous and benign items. Test setups are developed useful for

identifying the value of microwaves for shape detection behind selected material types.

The behavior of this electromagnetic energy in homogeneous, isotropic, locally linear,

temporally dispersive material is examined in the time and frequency domains. The

results of the evaluations determine the behavior of continuous-wave microwave

radiation and microwave pulses in such media. A unique method is then developed for

detecting the shape of concealed conductive objects utilizing pulsed microwave ultrawideband

spectra.
