Limitation of Precise Simulations of Handheld Mobile Phones with FDTD

The objective of this study was to assess the possible source of uncertainty of FDTD simulations of geometrically and electrically well-defined transmitters in the very close proximity of lossy scatterers. The study showed that FDTD is of limited use to conduct dosimetric evaluations of mobile phones, since relatively large safety margins of several dB are required due to the uncertainties in modeling the physical phone. On the other hand, numerical techniques complement efficient CAD tools to design and optimize antennas for mobile communications, since tight margins of absolute values are of minor relevance for design applications.
