Book Description
The application of impedance loading techniques for the reduction of backscatter from radar targets were studied. The hybrid methods which combine the GTD and the moment method were used to analyze the backscattering from various geometries such as impedance loaded infinite wedge and a two-dimensional wing model. The effect of both the trailing and the leading edge was considered by using a two-dimensional wing model. The edge diffraction source can be considerably reduced over a 3:1 frequency band for the two-dimensional case. The square plate with a loaded slot was analyzed by a wire grid model. The backscatter reduction of the square plate can be achieved at least over a 2:1 frequency band.

Book Description
An N-port loaded scatterer is one having N ports to which lumped impedance loads or a load network is connected. Methods are given to determine the characteristic modes of a loaded scatterer and for using them in a modal solution for electromagnetic scattering. A procedure is also given for resonating any given real port current, which makes that current the dominant mode of the loaded scatterer. The theory is formulated both in terms of open-circuit and short-circuit network parameters. A number of numerical examples are given for a wire triangle to illustrate the general theory. Computer programs are included for all procedures discussed. (Author).

Book Description
This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.
