Abstract :
A time-reversal approach to reconstructing the electrical parameters of an inhomogeneous object from measured total field data is considered. It is shown that the approach does not require the information of the incident field in the region of interest enclosing the object when the primary source is placed outside of the region. Numerical simulations are performed to validate the effectiveness of the approach.
