We describe a method of extrapolation based on a "truncated" Kramers-Kronig relation for the complex permittivity (ϵ) and permeability (μ) parameters of a material, based on finite frequency data. Considering a few assumptions, such as the behavior of the loss tangent and the overall nature of corrections, the method is robust within a small relative error, if the assumed hypotheses hold at the extrapolated frequency range.
