Due to the very specific electromagnetic properties of biological tissues, electromagnetic field calculation in the human body is difficult and the choice of the best numerical formulation is not straightforward. This question is analysed by solving a canonical problem: the scattering of a plane wave by concentric spheres. Electromagnetic properties of various biological tissues are considered to take into account the heterogeneity of the human body. Several finite element formulations are compared in the 10Hz-1GHz frequency range with respect to the analytical solution.
