FDTD Derivation of Effective Resistance for Grounded Human

摘要

According to the international guidelines, whole-body average specific absorption rate (WBSAR) is used as a metric for human protection. It is well known that WBSAR largely depends on the frequency of the incident wave. The frequency at which the WBSASR becomes maximal is called "resonance frequency". Our group discussed an estimation method of WBSAR for grounded humans at their respective resonance frequency in term of ankle current and effective resistance. This method is based on an analogy between a quarter-wavelength monopole antenna and human. Thus, it is essential to investigate the effective resistance for anatomically-based human models. In the present study, we calculated effective resistance for humans grounded on the perfect conductor, and then clarified its variability for different models. The main reason for the variability was attributed to the body shape and model anatomy.
