Cole–Cole Model for the Dielectric Characterization of Healthy Skin and Basal Cell Carcinoma at THz Frequencies [PDF]

IEEE Open Journal of Engineering in Medicine and Biology
THz radiationeffectively probes biological tissue water content due to its high sensibility to polar molecules. Skin and basal cell carcinoma (BCC), both rich in water, have been extensively studied in the THz range.

Cole-Impedance Model Representations of Right-Side Segmental Arm, Leg, and Full-Body Bioimpedances of Healthy Adults: Comparison of Fractional-Order

Fractal and Fractional, 2021
The passive electrical properties of a biological tissue, referred to as the tissue bioimpedance, are related to the underlying tissue physiology. These measurements are often well-represented by a fractional-order equivalent circuit model, referred to ...

Development of a Theoretical Microwave Model to Predict the Dielectric Properties of Articular Cartilage Tissues

IEEE Access, 2021
Recently, a growing research on the electromagnetic properties of biological tissues has been observed, particularly at microwave frequencies. The frequency variation of the dielectric properties of tissues at microwave frequencies may be described by ...

Time domain characterization of the Cole-Cole dielectric model

Journal of Electrical Bioimpedance, 2020
The Cole-Cole model for a dielectric is a generalization of the Debye relaxation model. The most familiar form is in the frequency domain and this manifests itself in a frequency dependent impedance.

Computation of Analytical Derivatives for Airborne TEM Inversion Using a Cole–Cole Parameterization Based on the Current Waveform of the Transmitter

Sensors, 2022
Airborne transient electromagnetic (ATEM) technology is a technique often used in mineral exploration and geological mapping. Due to inductive polarization (IP) phenomena, the ATEM response curve often shows a negative response or declines rapidly to the

On the role of the J-E constitutive relationship in applied geoelectromagnetism

Annals of Geophysics, 2003
In current applications of the Induced Polarization (IP) method, the Debye and Cole-Cole models are used to study relaxation and dispersion properties of rocks, though it is believed that this type of modelisation is confused and vague, because
