Specific absorption rate (SAR) evaluation of human body model in the presence of radar wave radiation on a warship deck

High power electromagnetic radiation may cause certain damage on human body working on a warship deck. Therefore, it is very important to accurately characterize such radiation effect so as to further protect the human body in an appropriate way. In this paper, finite difference time domain (FDTD) method together with the technique for treating dielectric boundaries is employed for numerically characterizing specific absorption rate (SAR) distribution of a human body model in the presence of high power radar wave radiation on the warship deck. In particular, the relations between SAR distribution and incident radar wave parameters are examined and compared, including the incident wave angle, polarization state and its strength. Also, accumulated power in the human body is evaluated as a function of incident or action time of the incident radar wave.
