摘要: The relevant properties of the human body from very high frequency (VHF) to X band are studied and dominant propagation modes around discussed in this chapter. Based on these data, approximate torso models built for each mode using multiple concentric cylinders emulating skin, muscle, organ, like. After study, a simpler two-layer model is proposed efficient calculations without loss accuracy used analysis epidermal sensor. radio (RF) tissues affect propagation, reflection, attenuation, other behaviors electromagnetic fields body. Body-centric wireless communications can be divided into three types based interaction between EM field. In case, different dominant.
