Electromagnetic Coupling Mechanism in a Layered Human Tissue as Benchmark for 434 MHz RF Hyperthermia Applicators

In order to minimize exposure to human tissue, electromagnetic interaction with antennas has benefited from a lot of research since hand-held communication transceivers became widely used consumer products. Motivated by safety concerns, much of the literature is focused on studies using communication frequencies. On the other hand, medical applications have been exploiting the ISM (Industrial Scientific and Medical standard) 434 MHz frequency band for therapeutic applications such as hyperthermia. In this case, reducing the size of the radiating applicator and efficient delivery of high powered electromagnetic energy without burning the skin (which adds to patient discomfort during the exposure) are priority considerations.
