Abstract
The possibility of terahertz imaging in medical applications is investigated by the design and implementation of an electromagnetic system. Numerical analysis based on the transmission line matrix method is used to obtain the shape or form of the biological object. The effect of different discretization parameters on the convergence of the transmission line matrix method is studied in detail. Exact and efficient dielectric profile image reconstructions of three dimension lossy scatterers from different complex cross sections using synthetic scattered field data are presented. The influence of antenna spacing and the suitability of the simplified transmission line matrix model for system evaluation are examined.
