TL;DR: A spatial iterative algorithm for electromagnetic imaging based on a Newton-Kantorovich procedure for the reconstruction of the complex permittivity of inhomogeneous lossy dielectric objects with arbitrary shape was proposed in this paper.

TL;DR: An iterative reconstruction algorithm based on the Levenberg-Marquardt method is tested with synthetic data and two methods for choosing the regularization parameter, an empirical method and generalized cross validation method, are examined.

TL;DR: A numerical method and experimental technique for microwave imaging of inhomogenous bodies is presented in this article, which is based on the interpretation of the diffraction phenomena and leads to tomographic reconstruction of the body under investigation.

TL;DR: In this paper, the problem of determining the shape and location of an object embedded in a homogeneous dissipative medium from measurements of the field scattered by the object is considered and two different reconstruction algorithms, a Newton-Kantorovich (NK) method and the modified gradient (MG) method whose effectiveness and robustness are compared.

TL;DR: In this article, a preliminary study of the application of simulated annealing (SA) to complex permittivity reconstruction in microwave tomography is presented, and the results show that SA can converge to an accurate solution in cases where the two deterministic methods fail.
