Spatial characterization of the electric field considering an optical three-dimensional scanned human body model

•The position specificity of the electric field around human body is analyzed.•Some energy absorption regularities were found.•It is found that creeping waves play a leading role in the space around the physical phantom.

Statistical channel models have been widely studied for body-centric wireless communications (BCWCs). Besides the channel models, the study of location specificity of the electric field is also highly important in understanding the communication phenomenon in this area; however, only few related studies have been done so far. In this paper, by applying the finite difference time domain (FDTD) method, the position specificity of the electric field is analyzed. Some energy absorption regularities were found, which are significant in designing receiving terminals for BCWCs.
