Abstract

In this paper a CAD tool for the automatic design of passive microwave components is described. It is based on a genetic algorithm optimizer and a three-dimensional finite element simulator. The main feature of the proposed tool is its ability, achieved by means of the parallel virtual machine software package, to fully exploit any concurrent computational resource. The effectiveness of the proposed approach is preliminarily assessed by considering the synthesis of a rectangular waveguide power divider. Selected numerical results confirm the capabilities, but also the current limitations, of the presented methodology. © 2002 Wiley Periodicals, Inc.

Abstract

In this paper, we explore the possibility of applying the moment method to determine the electromagnetic field distributions inside three-dimensional bounded non-linear dielectric objects of arbitrary shapes. The moment method has usually been employed to solve linear scattering problems. We start with an integral equation formulation, and derive a non-linear system of algebraic equations that allows us to obtain an approximate solution for the harmonic vector components of the electric field. Preliminary results of some numerical simulations are reported.

Abstract

This paper deals with the synthesis of planar arrays. In the framework of iterative search procedures, a method based on a genetic algorithm (GA) is presented. Starting from the definition of a suitably defined cost function, thinning and weighting a randomly generated array configuration, the multi-purpose stochastic procedure is able to satisfy various antenna constraints to determines an optimal trade-off among contrasting requirements. In order to confirm the reliability of the proposed approach (also in comparison with the related literature), some highly optimized antenna array designs are reported and discussed. © 2002 Wiley Periodicals, Inc.
