As the availability of Terahertz (THz) sources and their application expands, interaction with biological material needs to be well-understood. In order to accurately estimate the energy absorption pattern in skin and other tissues in the THz and far Infrared regions, values of dielectric parameters ϵ and σ are required. We present an approach for tissue water, which uses literature values of complex refractive index for pure water together with some considerations regarding the effects of dissolved salts. The approach also involves modeling of Debye and Lorentz absorption parameters, which provides a method for the estimation of ϵ and σ in other tissues.
