Summary:As an initial step towards developing a portable diagnostic system for skin cancer, an optimum fourth order Debye model for the human skin at millimetre-wave band is presented. The model is obtained using heuristic genetic algorithm, which enables the precise estimation of the dispersive nature of the human skin tissue when irradiated at a high frequency band of 10 GHz to 45 GHz. The precise derivation of the realistic skin model, having frequency dependent electrical properties, is essential for monitoring electromagnetic wave propagation and scattering in the simulation environment. The reported study indicates that the proposed model yields superior fitting to experimental results (error = 8.9e-4) compared to the existing first order Debye model (error = 5e-3) for the band in consideration.
