摘要

A Crawford transverse electro-magnetic (TEM), cell, used for RF exposure of in vitro cell cultures to examine any pathological effects, is modelled using an original high resolution finite-difference time- domain (FDTD) code at cellular handset frequencies. The standard scalar specific absorption rate (SAR) dosimetry parameter is augmented by new vector parameters of field polarization type and phase, and an easily comprehensible way of displaying these data as polar plots is used. It is shown that whilst the incident field in the empty TEM cell has plane wave properties, the exposure field in a blood sample is not a TEM plane wave, nor is it representative of the near field produced by a mobile handset.
