In this paper, the electromagnetic interaction between human skin and terahertz radiation is investigated through the double Debye parametersâ extraction algorithm. The changes of skin content are contrasted at the frequencies below one terahertz(THz) but the recent approaches could provide only a rough estimation. We propose an global optimization based identification, which results in globally accurate estimators in the frequency range up to two THz, and thus supports the validity of Debye model for Terahertz waveâs propagation and reflection in skin. Simulation results confirm our prominent methodology.
