Characterization of Human Skin Using THz Time Domain Spectroscopy for In-body Nanonetworks

In this paper, the intrinsic material properties of human skin via THz Time Domain Spectroscopy has been investigated in a working frequency range from 0.1-1.5 THz. These measured material parameters are utilized to characterize the channel in nano-networks. The sample for spectroscopic study is the real human skin and repeated measurements have provided consistent refractive index and absorption coefficient results. The refractive index in the working frequency range is 1.5, while abortion coefficient is 56 cm-1 at 1 THz
