Dielectric property measurements of biological tissues: Recent activityies for development of a novel database

The dielectric property values of biological tissues are used for the safety analysis and development of medical applications. A previous study conducted by Gabriel et al. has provided reference dielectric databases. To the best of our knowledge, no other databases have been constructed that allow a comprehensive measurement to be conducted with such a large number of tissues and organs. To this end, we present the development of a novel database for adaptation to recent research, permitting the validation of measured dataset by Gabriel et al. In this paper, we introduce measurement systems for further developing the database and summarize our findings with a discussion on the remaining challenges.
