Description
Summary:The key objective of this article is the development of a simple and computationally affordable nonspherical model of the infant torso for the accurate calculation of the electric field from a nearby-located external source. The new model consists of a multilayered host sphere containing four spherical inclusions for the representation of the different tissue groups. The electric field is then determined via simulations for a Hertz dipole at 2.4 GHz substantiating the merits of the model's simplicity. Furthermore, since the model comprises straightforward structures (i.e., spherical bodies), the electric field can be accurately derived by means of dyadic Green's functions (dGfs) for both a nonspherical and a spherical model with the results of the latter being used as inputs in various computational methods concerning more challenging arbitrarily-shaped models.
