Abstract :
In our paper, we calculated the distribution of an electric field modulus at several parallel cross-sections of a model heart (with a catheter inside of its right atrium). The catheter was created out of dielectric or metal material. The frequency of the microwave signal was f = 10 GHz. The distribution of the electric field modulus has resonance peaks. The electric field could be concentrated in different places of the heart depending on weather the material of the catheter was dielectric or metal.
