This method permits to obtain images of non-homogeneous dielectric objects whose dimensions are comparable to the incident wavelength. The feasibility of this method is showed in two synthetic examples using the CDM with 257 and 515 dipoles, for spherical objects with a spherical inclusion. The method also works if the scattered electric field, which is the input data, is corrupted with Gaussian noise.Submitted by Texeira Ana (atanateixeira@gmail.com) on 2012-09-12T15:07:01Z No. of bitstreams: 1 Bassrei, Amin.pdf: 197451 bytes, checksum: a7b8db27048c0b7dd743d2a3b15720b8 (MD5)Made available in DSpace on 2012-09-12T15:07:01Z (GMT).
