Abstract :
The aim of this paper is to find the fields inside a human head radiated by a point antenna source in close proximity to the human head. The human head is modeled as 3 layers of lossy tissue. The numerically efficient and accurate CIT is used to find the mixed potential Green´s functions with very good agreement between the numerical integration and the CIT results for log(KOρ) <; 1. The E-field and SAR inside the human head will be found from the mixed potentials and presented at the conference.
