We study the inverse problem of recovering the scatterer shape from the far-field pattern(FFP)in the presence of noise.Furthermore,only a discrete partial aperture is usually known.This problem is ill-posed and is fre...

Accurate simulations of metamaterial devices are very important in the analysis of their electromagnetic properties.However,it is very difficult to make full-wave simulations of three-dimensional(3D)metamaterial devic...
