An original iterative method based on the conjugate gradient algorithm is developed in this paper to study electromagnetic scattering. The Generalized Equivalent Circuit (GEC) method is used to model the problem and then deduce an electromagnetic equation based on the impedance operator. For validation purposes, the developed method has been applied to… (More)

In this work, we propose a microwave imaging technique for the localization and the shape reconstruction of physically inaccessible cylindrical conducting objects from the knowledge of the scattered electric field. The problem is treated with the Method of Moment (MoM) and the radial basis function neural network (RBF-NN) is applied. This linear RBF-NN has… (More)

This paper presents a new hybridization between MoM-GEC and some asymptotic methods. In fact, a new hybrid current function based on Physical Optic (PO) and a modal method is developed. The approach consists in approximating the total current on an invariant metallic pattern on two parts; the inside of metal is governed by PO method; however, the edges are… (More)

The present paper sets out to present a numerical electromagnetic (EM) method TWA for EM field modeling of planar structures. Combining both the benefits of TWA process and the modeling of planar excitation source, an optimization technique AMT is applied and evaluated in context of RF integrated-circuit applications. The computational complexity of TWA… (More)

This paper considers rerouting and minimization of incurred disruption due to rerouting in all-optical wavelength division multiplexed (WDM) network with dynamic (random) traffic arrivals and departures. One limitation of such a network is the wavelength continuity constraint imposed by the all-optical cross-connect switches which do not allow a circuit to… (More)

In this paper, an electromagnetic model based upon the method of auxiliary sources is developed around multilayered structures without any restriction of physical and geometrical macroscopic parameters. Thus, the multilayered structure is considered as a superposition of a finite number of strongly coupled and recovered layers. The extended method of… (More)

A multi-scale (MS) approach combined to the generalized equivalent circuit (GEC) modeling is applied to compute the input impedance of pre-fractal structures with incorporated PIN diodes. Instead of treating the whole complex problem at once, the MS method splits the complex structure into a set of scale levels to be studied separately. The computation is… (More)

In this paper, we propose a novel lightpath rerouting algorithm to optimize network resources allocation in WDM all-optical networks in order to set up an incoming lightpath demand to be blocked for lack of resources or due to the absence of a suitable path and a suitable wavelength that meet the minimum Quality of Transmission (QoT) requirements. Indeed,… (More)

Entropy, alpha, and anisotropy (H/α/A) parameters of the polarimetric target decomposition have shown their capacity for polarimetric synthetic aperture radar (SAR) image analysis. However, due to insufficient averaging, these parameters are biased. The literature shows that the anisotropy bias removal is not resolved. Based on simulation results, we… (More)
