The objective of this research is the electromagnetic characterization of biological tissues in radiofrequency domain. In this aim, a measurement bench including a vector network analyzer and an open-end coaxial probe was introduced. The complex permittivity identification of the middle under testing is performed by solving an inverse problem. A quadratic fitness function that represents the difference between reflection coefficient measurement and reflection coefficient acquired with the normalized aperture admittance is minimized. The optimization is based on a heuristic algorithm: particle swarm. The approach is validated on well known dielectric middle and then tested on biological tissues.
