Abstract :
In this paper we use Finite Difference Time Domain (FDTD) numerical technique and Physical Optics (PO) approximation in conjunction with phase conjugation method, for computation of transmitted field through walls and image formation. Using this model, different refocusing techniques can be investigated. Numerical results for imaging of target behind a solid block wall and cinder block wall are provided.
