Abstract

The problem of determining the shape of a variable conducting cylinder buried in a half-space by the genetic algorithm is investigated. Assume that a variable conducting cylinder of unknown shape and conductivity is buried in one half-space and scatters the field incident from another half-space where the scattered filed is measured. Based on the boundary condition and the measured scattered field, a set of nonlinear integral equations is derived and the imaging problem is reformulated into an optimization problem. Keywords: inverse scattering, genetic algorithm, variable conducting cylinder. 1 Introduction The image problem of conducting objects has been a subject of considerable importance in noninvasive measurement, medical imaging, and biological application. In the past 20 years, many rigorous methods have been
