Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 746)

Abstract

The importance of an accurate dielectric model for the blood permittivity, both in terms of real part as well as of imaginary part, when changing the glucose level, is properly highlighted in the present contribution, with the aim to improve the performances of non-invasive microwave glucose sensors. A Cole-Cole based enhanced dielectric model, properly correcting the imaginary part of blood permittivity to include the glucose changes dependency, is proposed. Preliminary numerical validations of the presented approach, and comparisons with existing models, are discussed.
