Power-law picture for the interpolation of AC-DC differences in thermal standards

Abstract

In this work we present a general method, commonly applied to the numerical analysis of stochastic models, to interpolate AC-DC differences (usually denoted by the greek letter δ) between calibration points in thermal transfer standards. This method assigns a power-law behaviour to AC-DC differences, solely under the assumption that δ must be some smooth-varying function of voltage and frequency. We argue it may be straightfowardly applied to all working ranges of the standards, with no distinction.
