Numerical Modeling: Integral Equation Method,

Abstract

A review is given to the different expressions for the representation of the electromagnetic fields by integrals over the surface current. The integral equations, which mostly are used for the solution of practical problems, are discussed and the method of moments is outlined, where the use of pulses as basis functions is emphasized. Estimations of the core storage and the computer time are given. Two geometrical models for the scattering structure are discussed in more detail: the surface patch model and the wire-grid model. A list of application examples of the integral equation method with references is given. Two further examples are outlined in detail: computation of the radiation pattern of an antenna mounted on a helicopter and determination of the extreme near field of a cube. (Author)
