Techniques de maillage non uniforme dans la Mthode des Moments: Caractrisation des structures planaires (Omn.Pres.Franc.) (F,Used
Delivery time: 8-12 business days (International)
Dans ce travail une technique efficace pour valuer les intgrales contenues dans la matrice des moments est dveloppe pour l'analyse des structures planaires. L'quation intgrale aux potentiels mixte (MPIE) est rsolue par la MoM en utilisant les fonctions de base RWG (RaoWiltonGlisson) dfinies sur les cellules triangulaires. Les intgrales quadruples de raction pour chaque lment de la matrice des moments sont rduites des intgrales doubles par lutilisation de laveraging approximation . Avec la centrod integration les intgrales doubles ont t rduites une forme trs simple qui exige seulement l'valuation des fonctions de Green et des oprations arithmtiques simple. Lhybridation des deux procdures ainsi que lutilisation de la forme closed form des fonctions de Green ont permis dviter lvaluation analytique des intgrales. Le gain en temps de calcul est trs important : 93% compar la technique MoM classique.
