Medical applications of high-frequency electromagnetic fields

Medical applications of high-frequency electromagnetic fields

The group studies medical applications of high frequency electromagnetic fields, e.g., microwave thermal ablation. Conducted studies include dosimetry of electromagnetic fields, microwave thermal ablation, hyperthermia, tissue dielectric properties characterization, as well as microwave imaging. As an example, studies are conducted to experimentally determine the dependence of dielectric and thermal properties on the temperature, and to develop numerical models representative of the electromagnetic field and temperature evolution in microwave thermal ablation procedures.

Impact of textile on electromagnetic power and heating in near-surface tissues at 26 GHz and 60 GHz

With the development of 5th generation (5G) networks the operating frequencies have been progressively expanding towards millimeter waves (MMW). In some exposure scenarii, presence of textiles impacts the interaction of the electromagnetic field radiated by wireless devices with human tissues. We investigate the impact of a textile layer in contact or in proximity of skin on the power transmission coefficient, absorbed power density and temperature rise using a near-surface tissue model at 26GHz and 60 GHz. Cotton and wool are considered as representative textiles.
