The human body modelled by canonical geometric shapes for the analysis of scattered E-fields

Résumé

The objective of this paper is to propose a simplified model of a human body to be used in electromagnetic problems involving high frequency field scattering. Canonical geometric shapes, analytically described, represent the body. The accuracy of the model was tested comparing the field scattered by the simplified body representation with the one scattered by a more realistic phantom. At first, the influence of anatomical details of the body was analysed, comparing the electromagnetic field reflected by a realistic human head with the backscattering of spheres and of an ellipsoid. A second test concerns the human body, modelled by sphere, parallelepiped and cylinders. In this case, the possibility of reconstructing a wideband pulse scattered by the whole body with the superposition of pulses scattered by its separated parts was demonstrated. Both analyses were carried out in the frequency range 3-5 GHz using a full wave numerical simulator.
