摘要:
An efficient calculation method for the radiation performance of hand-held mobile telephones is proposed. It enables an accurate modelling of any complex antenna and any case structure to calculate input impedance, SAR values inside the head, and electric and magnetic near-fields and far-fields. The head of the user is approximated by a layered homogeneous lossy dielectric sphere.
