3D modelling of electromagnetic time-reversal localization of a dielectric object in a half-space
Résumé
This paper presents a 3D full time-domain modelling of the time reversal process for the localization of a dielectric obstacle buried in an homogeneous half-space using an array of dipoles. The main purpose of this study is to propose a local- ization method based on the analysis of the ElectroMagnetic (EM) energy of the back-propagated fields. A Generalized Finite Difference (GFD) method and a leapfrog time dis- cretization are used to get the numerical results.
