The geometrical theory of diffraction (GTD) is an efficient method of analysis and design of
wave fields. It is widely used in antenna synthesis in microwave, millimetre and infra-red …

The method of matching pursuits utilizes a nonlinear iterative procedure to project a given
waveform onto a particular dictionary. For scattering problems, the most appropriate …

A superresolution signal processing algorithm is used for the identification of wavefronts
from the fields scattered from several canonical targets. Particular wave objects that are …

A method-of-moments (MoM) analysis is applied to the problem of determining late-time
resonances of dielectric bodies of revolution buried in a lossy layered medium, with …

We review progress in identification of electromagnetic systems. We introduce the basic
ideas with a brief discussion of forward and inverse problems. We next give some history …

Wavefronts and resonances form alternative descriptions for transient scattering by targets,
with the former most effective at early observation times and the latter most effective at later …

The complexity of transient electromagnetic scattering from objects in free space has been
well known for years. Such complexity is mainly due to the high aspect dependency of the …

Time-frequency (TF) analysis of a transient electromagnetic signature from a radar target is
conducted. Using an example of a bent wire target, it is demonstrated that the evolution of" …

The resistivity method in cased boreholes with downhole current sources is investigated
using the integral equation (IE) technique. The casing and other bodies are characterized as …

By including correction terms in inverse powers of the wavenumber k, one may hope to
extend the range of applicability of multiple edge diffracted geometrical theory of diffraction …
