Abstract :
Presents a finite element approach to determine the dissipated power density in the heart chambers during microwave ablation for the treatment of heart rhythm disorders. Two full wave electromagnetic problems are solved: a generalized eigenvalue one that determines the modes of propagation in the feedline and a radiation one that determines the electric field in the catheter, the blood, the myocardium, and the torso
