Book Description
The problem of determining the scattered electromagnetic field produced when an initially quiescent incident field impinges upon a perfectly conducting body moving and deforming in vacuum is originally formulated as an initial-boundary-value problem for Maxwell's equations in a noncylindrical exterior domain in space-time. The motion and deformation of the scatterer are allowed to be fairly general, the essential hypotheses being that the boundry of its space-time track is smooth and can be mapped and smoothly onto a cylinder, while the speeds of points on the body must remain less than that of light in vacuum. Within this setting, uniqueness theorems are proven for various initial-boundary-value problems for a system of generalized Maxwell equations (in particular, for the scattering problem), and for the scalar wave equation, in noncylindrical domains.

Book Description
The purpose of the work is to describe a theoretical formulation, including a documented computer program, for the evaluation of electromagnetic scattering by perfectly conducting bodies having an axis of rotational symmetry. The main body of the work gives the theory, which has been modified considerably from that given earlier. Appendix 1 gives the analysis and logic which forms the basis for the various subroutines of the computer program. Appendix 2 gives the complete FORTRAN listings of the computer program. Finally, Appendix 3 gives the computer printout for a numerical example, scattering by a conducting sphere-cone-sphere obstacle, as obtained on the IBM 7030 digital computer. (Author).

Book Description
The book represents an exhaustive study of the scattering properties of acoustically soft and hard bodies and of perfect conductors, presented for 15 geometrically-simple shapes. Such shapes are important in their own right and as a basis for synthesizing the radiation and scattering properties of more complex configurations. Each shape is treated in a separate chapter whose contents are presented in stylized format for easy reference. Emphasis is placed on results in the form of formulae and diagrams. Although no detailed derivation are included, an outline of methods in scattering theory is given in the Introduction. (Author).

Book Description
In this work, the problem of electromagnetic scattering of a plane wave incident on a conducting body of revolution is considered. The body is assumed to be situated in infinite homogeneous space. The problem is solved using the method of moments. Use of two different types of expansion and testing functions, namely, sub-domain type and entire-domain type is considered. Results obtained using sub-domain pulse functions and entire-domain Gaussian functions are presented. The relative advantages and disadvantages of each type of basis functions is discussed. Keywords: Electromagnetic scattering, Method of moments, Bodies of revolution, Entire domain functions, Subdomain functions.
