Rezumat
Lucrarea prezinta o aplicatie a Metodei Iterative Bazata pe Conceptul de Unda (WIP) in cazul studiului difractiei
unei unde electromagnetice plane pe suprafata unui obstacol metalic 3D. Aplicatia este realizata in scopul validarii Metodei Iterative in cazul unei probleme clasice de difractie. Se trateaza Cazul unui obstacol difractant sferic. Se studiaza convergentele modala si iterativa. Se evalueaza densitatea de curent de pe suprafata sferei, rezultatele obtinute fiind
comparate cu solutia analitica exacta disponibila pentru acest caz particular.

Abstract
The paper presents an application of the Wave Iterative Process (WIP) in the case of the study of the scattering
of an electromagnetic plane wave by a metallic 3D obstacle. The application is made in order to validate the original Iterative Method for a classical metallic obstacle diffraction problem. The case of a spherical scatterer is treated. Modal and
iterative convergences are studied. Current density is calculated and compared with the exact solution available for this
particular case.
