This procedure is performed by evolving an initial-guess object iteratively until the cost function decreases to a desired value. Rapid convergence of this method is demonstrated by some numerical results.EnglishConvergence of numerical methodsCost functionsIterative methodsNumerical methodsDielectric objectsElectromagnetic imagingInitial guessInverse scattering problemsNewton minimizationNumerical resultsRapid convergenceUnknown objectsInverse problemsConference Paper10.1109/APS.2014.6904766
