“…Among all the possible solution techniques, analytical approximation techniques [11][12][13] and layer stripping techniques [14,15] can be especially emphasized. Most often, the profile reconstruction problem is solved by an optimization method that minimizes the error between the observed and calculated data.…”

The problem of reconstruction of a one-dimensional profile of gradient layer's refractive index is investigated. An algorithm for choosing a right frequency, at which a scattered field is measured, is proposed. It is concluded that at the correct choice of frequency one measurement must be sufficient. Moreover, in this case, regularization parameters of the residual functional are chosen as zero. It is shown that in case of measurements being carried out with errors, residual terms must be added to the functional.

“…The term direct based inversion means that the electromagnetic properties of the medium are obtained from direct calculations applied to the scattered data. These methods include analytical approximation techniques [1][2][3] and layer stripping techniques [4,5]. Model based methods try to match the data calculated from the forward problem with the data obtained from the measurements or simulation process.…”

Abstract-An electromagnetic inversion method is proposed for the reconstruction of lossy dielectric slabs. The inversion is done using particle swarm optimization hybridized with Quasi-Newton algorithm. The inversion process is applied to reconstruct dielectric slabs with discrete or continuous profiles. Accurate reconstruction of lossy dielectric slabs is obtained from inversion of reflection coefficient data of normally incident plane waves in the specified frequency range.The proposed algorithm is also tested using noisy data and showed satisfactory performance.
