MOMENT-METHOD MODELING OF SHORT-PULSE SCATTERING FROM AND THE RESONANCES OF A WIRE BURIED INSIDE A LOSSY, DISPERSIVE HALF-SPACE

A frequency domain method-of-moments (MoM) algorithm is used to model short-pulse plane-wave scattering from a wire buried inside a lossy, d ispersive half-space with the time-domain scattered fields computed vi a Fourier transform. Further, the complex resonant frequencies of such targets are also calculated via the MoM. The phenomenology associated with scattering from a buried wire is investigated in detail, and it is demonstrated that the time-domain scattered fields and the target r esonances depend on the buried-wire orientation as well as the electri cal properties of the half-space.
