Analyse du résonateur transverse électromagnétique en cage d’oiseau par la méthode des éléments finis

Abstract

Finite Element Analysis of The Transverse Electromagnetic Birdcage Resonator

In this paper we have successfully  realized a numerical tool to analyze an n-element unloaded microstrip line transverse electromagnetic (TEM) resonator for magnetic resonance imaging. This numerical tool allows the determination of the primary parameters: [L], [C] and [R] matrices witch permit the design and the simulation of the frequency response at the RF port of the IRM probe. As an application, we present the results obtained by Finite Element Method (FEM) analysis of a 12 elements.
