A Polarizability Matrix Representation of Electrically Small Obstacles

Abstract

A polarizability matrix representation is developed to describe the interaction of a plane electromagnetic wave with a loss-free body of arbitrary shape and small electrical size. This matrix is used to express far scattered fields in terms of six induced dipole moments - three mutually orthogonal dipoles of electric type and three mutually orthogonal dipoles of magnetic type. The matrix elements are evaluated from scattering data obtained by an independent method, such as the method of moments. Some numerical results for a variety of wire structures are presented in graphical form and compared with results obtained by numerical solutions to the corresponding boundary value problems.
