Table 4 Debye parameters optimized for tendon/collagen type I about the average tissue composition reviewed by Duck [17] and regarding the average dielectric tendon characteristics collected by Gabriel and co-workers [29], our golden standard. We propose to use these parameters to reproduce the complex permittivity (ε′ and σ) of a generic human tissue based on its water and solid content (see Supporting information, Eq. (S2))
