Application of the Subspace-based Optimization Method in the framework of the Method of Moments: Transverse electric case

The application of the subspace-based optimization method (SOM) in the framework of the method of moments (MoM) is presented so as to reconstruct the relative-permittivity profiles of extended scatterers in transverse electric case. The results of numerical experiments confirm that the SOM is rapidly convergent, robust against noise, capable of reconstructing objects of complex shapes.
