| Research Abstract |
Iterative reconstruction algorithms of visualizing the material parameters inside a concrete structure are presented. The scattered electromagnetic wave from the concrete structure is obtained by using the moment method or the FDTD method. Numerical results for a lossy dielectric cylinder and a dielectric scatterer inside a homogeneous concrete show that the proposed algorithms provide good reconstructions of the material parameters.
