Abstract
Specific absorption rate (SAR) calculation using a computer-aided design (CAD)-based mobile phone model is still a challenging task. Seven international laboratories participated in an interlaboratory comparison of SAR calculations using a CAD-based model of a commercially available dual-band mobile phone. Return loss and peak 10 g average SAR results obtained using six different electromagnetic solvers were compared. Considering the differences in the techniques implemented in the solvers-either time or frequency domain-used for the interlaboratory comparison, overall a good agreement is observed. Proposed as a benchmark, results of the measured return loss and peak 10 g average SAR using the actual mobile phone are also provided.
