Abstract :
This paper presents the studies of time domain inverse scattering for a two dimensional inhomogeneous dielectric cylinder buried in a slab medium by the finite difference time domain (FDTD) method and the asynchronous particle swarm optimization (APSO) method. The APSO is applied to reconstruct permittivity of the two-dimensional inhomogeneous dielectric cylinder. Numerical result shows that APSO is able to yield good reconstructed quality.
