Caorsi, Salvatore and Massa, Andrea and Pastorino, Matteo and Donelli, Massimo (2003) Improved Microwave Imaging Procedure for Non-Destructive Evaluations of Two-Dimensional Structures. UNSPECIFIED. (In Press)
Abstract
An improved microwave procedure for detecting defects in dielectric structures is proposed. The procedure is based on the integral equations of the inverse scattering problem. A hybrid Genetic Algorithm is applied in order to minimize the obtained nonlinear functional. Since in nondestructive evaluations the unperturbed object is completely known, it is possible off-line to numerically compute the Green's function for the configuration without defects. Consequently, a very dignificant computation saving is obtained, since the 'chromosome' of the Genetic Algorithm codes only the parameters describing the unknown defect.
