Members of 3BAtwin from GALWAY published a new research paper titled “Dielectric Models of Normal and Diseased Human Trabecular Bones at Microwave Frequencies” on IEEE Open Journal of Antennas and Propagation.
This paper has developed the one-pole and two-pole Cole-Cole and Debye models for the dielectric properties of normal and diseased human trabecular bone tissue at microwave frequencies (0.5 – 8.5 GHz). The dielectric properties of normal trabecular and cortical bone were derived based on the literature, while those of diseased human trabecular bones (osteoporotic and osteoarthritis) were acquired from a previous study conducted by the authors, which characterised the properties within the 0.5 – 8.5 GHz frequency range. The proposed models can be used in numerical simulations to investigate the interaction of EM fields with bone tissue and develop and optimise microwave bone health monitoring and treatment techniques.
The paper is still in early access but it is openly available here.
