Abstract :
A time-reversal approach is developed for reconstructing electrical parameters of a stratified slab from time-domain reflection and transmission data. The impressed source as well as the equivalent sources corresponding to the measured reflected and transmitted fields are time-revered. Numerical simulations are performed to reconstruct an image of a stratified dielectric slab.
