Abstract
In the framework of NDE/NDT, this paper presents an innovative microwave diagnostic approach based on the use of the SMW inversion procedure for the electric field prediction. Starting from the integral form of inverse scattering equations, the problem of determining the presence of an unknown defect in a known host domain is recast into an optimization one by defining a suitable cost function and reducing the problem unknowns only to the flaw descriptors. By considering an effective inversion technique based on the SMW formula, the estimation of the secondary unknowns (namely, the electric field distributions) is performed in a cost-effective way. Selecte3d numerical results are presented to validate the approach showing current potentialities and limitations. For completeness, an application to civil engineering is also reported.
