Broadband Complex Permittivity Determination for Biomedical Applications
Original language description
The chapter deals with an electrical description of biological tissues, analysis of the reflection coefficient measurement method, feasibility study of different measurement probes, development of model for numerical modeling and simulations and experimental measurement of various biological substances for applications in the basic research on biological effects of electromagnetic fields and for medical diagnostics and imaging. A non-destructive and non-invasive method based on the reflection coefficient measurement is used. Relation between the reflection coefficient and complex permittivity is derived using the Deschamps? theorem. Two types of coaxial probes are under investigation and feasibility study of waveguide probes is presented. Vector measurements of the reflection coefficient are performed in the frequency range from 300 kHz to 3 GHz. Numerical modeling is compared with measurement. Measurement uncertainty is evaluated.
