Ex-vivo Dielectric Properties of Tissues in Athymic Nude Mice

Measuring and reporting the dielectric properties of tissues remains a key area for microwave imaging and sensing, providing solid foundation for biomedical research in the field. In this study, the dielectric properties of tissues in athymic nude mice were evaluated. Measurements were conducted on liver, skin, muscle, and fat tissues using the co-axial probe technique within the microwave range between 500MHz–4GHz. The results demonstrate the distinct profiles for specific tissues as well as the variation that can be observed between individual animals. Notably, we evaluated fat samples from two distinct locations: from the abdomen and fat in close proximity to the tumour. It was observed that the location of the fat tissue can have an impact on the measured dielectric properties.
