The electromagnetic modeling of human tissues for biomedical purposes is a challenging task which usually requires large computational resources to take into account the complex properties and detailed structures of actual bodies. This is especially true if the modeling of tumor pathologies yielding anomalous microwave behaviour is of interest (as it happens for prostate cancer). In this framework, effective models have been recently proposed in order to enable the fast simulation of pathologies. Unfortunately, describing human bodies through traditional materials does not usually enable accurate modeling of the anomalous microwave response of pathological tissues. Accordingly, innovative electromagnetic models of biological tissues are of great importance in for the development of medical instruments working in the microwave range (e.g., tomography, radiotherapy).
Development of medical instruments working in microwave range, simulation and testing of innovative therapies (e.g., radiotherapy).


Electromagnetic Model Of The Abdomen
Members of the ELEDIA Research Center have developed innovative electromagnetic models for the effective simulation of biological tissues, which are based on the introduction of Metamaterial (MTM) inclusions in traditional numerical models. The motivation for this choice relies both on the microscopic structure of several tumor pathologies, which comprises "microfilaments" acting as resonators, as well as on the the observation of the macroscopic electromagnetic response of actual pathologies, which point out "EM focusing" properties typical of MTMs. The research activities carried out in this area have been focused on the mathematical modeling, implementation, and simulation of MTM-based models of biological tissues. Moreover, the exploitation of the developed models for inversion purposes is at present under investigation.
