“…Figure 5 shows that the polarized current Jp equation (25) evaluated by the GEC and obtained at convergence is conform to theory with respect to the boundary conditions. It shows that the current convergence is obtained for n=200 basis functions that the Gibbs effects are suppressed [6].…”

In this paper, we develop an electromagnetic analysis of a rectangular waveguide loaded with a dielectric model that is composed of a leaf plant with a neglected thickness. One numerical method is used for modeling the proposed structures: the moment method combined with Generalized Equivalent Circuit (MoM-GEC). We can determine the wave diffraction according to the dielectric properties. Our obtained electromagnetic field verified the boundary condition.

“…These oscillations resulting from truncation are due to the Gibbs phenomenon. Because of this effect, we cannot write the boundary conditions in the immediate neighbourhood of the metal-dielectric plane [24,25]. Figure 8 represents the magnitude part's numerical value of the input impedance behavior against the frequency for different discrete spectral values corresponding to a finite case composed of (2 × 2) elements in periodic array.…”

Abstract-Studying of mutual coupling parameters between the antenna elements in an array environment has been considered as the subject of feature research. That is why, in this paper, we present a new Floquet modal analysis procedure for analyzing almost periodic structures. Accurate evaluation of the mutual coupling could be achieved by this analysis. It is shown how Floquet analysis can be exploited to study a finite array with arbitrary amplitude and linear phase distribution in both x-y directions including mutual coupling effects. Two different calculation methods of coupling coefficients between the array elements are presented, in spectral and spatial domains, to solve the suggested problem. For modeling the given structures, the moment method combined with Generalized Equivalent Circuit (MoM-GEC) is proposed. High gain in the running time and memory used is given using Floquet analysis. To validate this work, several examples are shown.

“…It is shown that the current convergence is obtained for 300 basis functions in which the Gibbs effects are practically suppressed, and these oscillations resulting from truncation are due to the Gibbs phenomenon. Because of this effect, we cannot write the boundary conditions in the immediate neighbourhood of the metaldielectric plane [25].…”

Abstract-This paper proposes a new modal analysis based on Floquet's theorem which is needful for the study of a 1-D periodic phased array antenna excited by arbitrary located sources. This analysis requires an accurate estimation for calculation of the mutual coupling parameters (for example: mutual impedances or admittances . . . ) between the array elements and their effects integrating a large planar radiating structure. Two different formulations are suggested, in spectral and spatial domains, to solve the problem and to calculate the coupling coefficients between the neighbouring elements in a periodic environment. Important gain in the running time and used memory is obtained using Floquet analysis. One numerical method is used for modeling the proposed structures: the moment method combined with Generalized Equivalent Circuit (MoM-GEC).
