A rigorous full wave technique based on the Transverse Wave Concept Iterative Procedure (WCIP) is used to design a complex Frequency Selective Surface (FSS). These surfaces include a periodically arrangement of identical circuit. There are used as filters and reflector antenna as well as deep-space exploration for multi-frequencies operations. A simple FSS structure is studied in the first stage to validate our approach. In the second stage two different complex structures are studied. The good agreement between simulated and published data justifies the design procedure.

“…In the two cases, a good agreement is obtained between results. For the s onator circu nd example is represented in Figures 8 and 10 econd application, we consider res its optimized by the genetic algorithm [8] included in WR90 waveguide (a = 22.86 mm, b = 10.16 mm) The TE01 mode is used as excitation and the iterative process is stopped after 200 iteration. This circuit is used as a filter.…”

“…This paper presents the analysis of simple and complex passive FSS by the iterative method (WCIP). The WCIP technique takes the advantage of simplicity in its procedure based on Fast Modal Transform (FMT) in passage between spatial and spectral domain [8,9]. In addition, there is no matrix inversion was required and the convergence was insured independently of the circuit complexity.…”

“…This is proven in several research works. [1][2][3][4][5] The iterative method is absolutely convergent, [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] but in some cases of electronic circuits the number of iterations required to reach a stable value is relatively high. The numerical complexity of the studied circuit is related to the number of cells describing the structure requiring a fine mesh.…”

In this research paper, adaptive filtering techniques are used to improve performance of the wave iterative method. This method is used for the modeling and the study of the planar microwave electronic circuits which are the most used today in the new technologies of radio frequency communication. In order to improve the convergence speed of the wave iterative method, we use the recursive least square algorithm and the stabilized fast transversal filter. A significant gain in computation time is obtained with these new techniques with a good accuracy in the found results.
