Investigation into the Accuracy, Efficiency and Applicability of the Method of Moments as Numerical Dosimetry Tool for the Head and Hand of a Mobile Phone User

摘要

In this paper the Method of Moments (MoM) as numerical SAR assessment tool is investigated. Models for generic mobile phones operational at 900MHz and 1800MHz were developed. Simulations were performed using these phone models to investigate the accuracy and efficiency with which the MoM can predict field values inside lossy, dielectric test phantoms. Results obtained are compared to Finite Difference Time Domain (FDTD) simulations using the MoM were further performed using the generic phones, a parametric hand model and the preliminary standardised IEEE head phantom. Peak-SAR results are extracted from the MoM solutions and compared for different phone and hand positions, as well as with FDTD results where applicable.
