Rezumat
Metoda elementului de circuit partial echivalent (PEEC) este o tehnica de modelare integrala utilizata pentru
rezolvarea problemelor de camp si circuit atat in domeniul timp cat si in domeniul frecventa. Metoda se bazeaza pe
conversia ecuatiei integrale de camp electric in elemente de circuit partiale. In domeniul de frecventa s-au evaluat erorile introduse atat de calculul elementelor de circuit partiale cat si de inversarea matricii Analizei Nodale Modificate. In
domeniul timp rezultatele numerice au fost comparate cu cele din PSpice. A rezultat o buna concordanta intre valori.

Abstract
Partial equivalent element circuit (PEEC) is a full wave technique used for solving mixed electromagnetic field
and circuit problems in both time and frequency domain. The method is based on Electric Field Integral Equation (EFIE)conversion to partial circuit elements. The errors introduced by simplified formulas and different numerical techniques in partial element calculation and in the inversion of the Modified Nodal Analysis (MNA) sparse matrix, in frequency domain,
have been evaluated. The results in time domain were compared with the PSpice solver. Good agreement was found
