Electromagnetic (EM) wave scattering is of fundamental importance to antenna and radar design engineering, and the increasing interest in metamaterials has created a need for new approaches to solving scattering problems for characterizing engineered media. This book lays the theoretical foundation for new computer programs in computational electromagnetics (CEM) and meets the need of today's researchers. This book represents over 30 years of the author's experience teaching this topic, with extensive lectures notes expanded to include advanced concepts and mathematical solutions to cover modern effects on metamaterials and related advanced complexities. Problems and solutions at the end of each chapter help to reinforce concepts and highlight applications. This is an ideal text for advanced graduate students and researchers in EM and applied physics.

Plasma Scattering of Electromagnetic Radiation covers the theory and experimental application of plasma scattering. The book discusses the basic properties of a plasma and of the interaction of radiation with a plasma; the relationship between the scattered power spectrum and the fluctuations in plasma density; and the incoherent scattering of low-temperature plasma. The text also describes the constraints and problems that arise in the application of scattering as a diagnostic technique; the characteristic performance of various dispersion elements, image dissectors, and detectors; and the general scattered spectrum for an unmagnetized, low-temperature, quasi-equilibrium plasma. The application of the general scattered spectrum for a magnetized plasma; the scattering from a high-temperature plasma; and the scattering from unstable plasmas are also encompassed. Plasma physicists and people involved in the study of electromagnetic radiation will find the book invaluable.

The Scattering of Light and other Electromagnetic Radiation covers the theory of electromagnetic scattering and its practical applications to light scattering. This book is divided into 10 chapters that particularly present examples of practical applications to light scattering from colloidal and macromolecular systems. The opening chapters survey the physical concept of electromagnetic waves and optics. The subsequent chapters deal with the theory of scattering by spheres and infinitely long cylinders. These topics are followed by discussions on the application of light scattering to the determination of the size distribution of colloidal particles. The last chapters are devoted to the Rayleigh-Debye scattering and the scattering by liquids, as well as the concept of anisotropy. These chapters also describe the effect upon light scattering of partial orientation of anisotropic particles in electrical and magnetic fields and in viscous flow. This book is of value to physical chemists and physical chemistry researchers, teachers, and students.

The objective of the contract was to carry out a theoretical investigation of the scattering of an incident plane electromagnetic wave by perfectly conducting bodies of somewhat irregular shape. The results were to be applicable in the so-called resonance region, where the major dimensions and of the order of a free-space wavelength in size. The objects which were investigated included a cone of finite height, a circular cylinder of finite length, a cube, a finned circular cylinder of infinite length, a finned sphere, and a hemisphere. Solutions and numerical results for the radar cross section were obtained for the finite cone, the finned cylinder, and the finned sphere. The solution for the hemisphere has been obtained and numerical results are in the process of being secured. Some attention also was given to the problem of altering the scattering characteristics of reflecting objects without altering their essential configurations. Results were obtained for scattering by a long wire. (Author).

The theory of the scattering of electromagnetic radiation in the transverse magnetic mode by infinite plasma cylinders with radially varying electron-density distributions is reviewed. Techniques for calculating the scattering cross section are described, with special emphasis placed on short wavelength scattering. Specific calcu lations of the back-scattering (radar) cross section are made in the geometrical-optics limit and in the Born-approximation limit for several monotonically decreasing electron-density distributions which have zero slope on the cylinder axis. The radar cross section in the region of transition from underdense to overdense plasma is programmed and computed on the IBM 7090 for a Gaussian and for a quadratic electron distribution for wavelengths equal to 1/10 and 1/100 of the cylinder radius.

The principal purpose of the research is to investigate radio wave scattering and depolarization by conducting objects of irregular shape. To test the programs and in order to develop better physical interpretations of the results, scatterers with simple shapes are considered first. Thus, the full wave solutions for scattering and depolarization are compared with known solutions to the problem. The second phase of this work is devoted to the problem of scattering and depolarization by irregularly shaped objects. Both one- and two-dimensional problems are considered. To account for medium losses the scatterer is characterized by a complex permittivity and permeability. Using the full wave approach it is not necessary to employ the approximate impedance boundary conditions. Special attention is given to determining the normalized co-polarized and cross-polarized backscatter cross section. The full wave solutions for the scattering cross sections are compared with the perturbational and physical optics solutions. Special attention is also given to the polarization dependence of the scattering cross sections.
