Contactless Dosimetry with a Regularized Integral Equation Based Method

Résumé

This talk will present a source inversion algorithm that is capable to recover the field within a model of the human head in the presence of a radiating source (such as a mobile phone), starting from external field measurements and without a need for the numerical modeling of the source. The latter in fact will be replaced by an appropriately chosen simplified model that will avoid the detailed characterization of the electrically irrelevant details. This aspect of the method will be especially important for complex, hard to discretize and model, sources such as all the commercially available mobile phones. Moreover, differently from other inverse source formulations, the approach we are proposing relies on suitably regularized integral formulations both for modeling the dielectric parts and for discretizing the Helmholtz screens. The new regularized formulation is leveraging on a newly developed hierarchical spectral partitioning. The formulation has conditioning properties that are completely independent on the discretization density. This allows for the source to reside very near to the human head phantom under study.
