Abstract

This paper considers microwave imaging of parallel perfectly conducting cylinders using a solution of the scattering problem by the point‐matching method. A cubic B‐spline, real‐coded genetic algorithm and an adaptive hybrid algorithm are proposed to solve the inverse problem. Previous shape functions in trigonometric series with arbitrary coefficients are nondefinite, which intensify the ill‐posedness and slow the early time convergence of the algorithm. A novel shape function based on cubic B‐splines is developed and the real‐coded genetic algorithm is modified accordingly. Numerical simulation examples show that the early time convergence of the real‐coded genetic algorithm is improved significantly. Next, the adaptive hybrid algorithm is developed to improve the late time convergence of the cubic B‐spline real‐coded genetic algorithm. © 2001 John Wiley & Sons, Inc.

## Abstract We consider the scattering of a plane time‐harmonic electromagnetic wave by a perfectly conducting infinite cylinder with axis in the direction k, where k is the unit vector along the z axis. Suppose the incident wave propagates in a direction perpendicular to the cylinder. For a given
