“…The iterative method was developed in various theses and multiple articles [5][6][7][8], it is based on two types of waves, incidental (A k ) and reflected (B k ), respectively expressed in the space and modal fields, by the relations (6) and (7). The passage of these waves from one field to another is ensured by the iterative process using the fast modal transform (FMT), which is not other than the FFT balanced on each mode.…”

Abstract-In this article, we developed a new method of calculation of the active microwaves circuits in micro ribbon technology. This technique is based on the iterative method where localised auxiliary sources are introduced to model the active elements of the circuit (ultra high frequency diodes). To validate this work, the results obtained are compared with those obtained by the software momentum of advanced design system (ADS). We show primarily the interests and the operational limits of auxiliary source in the formulation of the considered problem.

“…Despite the performance achieved, the simulation results stayed slow in terms of CPU time. These various limitations can be redressed using the method of moments (MOM) [14,15] and an advanced transverse wave approach (A-TWA) [16,17] in the context of the EM-simulation of RF/microwave applications.…”

The art of benchmarking study has improved at an astonishing rate the scientific research in all areas but mainly in microwave engineering domain, and in particular, the field of microwave (MW) and radiofrequency (RF) integrated circuit design. Moreover, the fast simulation of complex MF/RF structures is considered a big challenge for the simulators, mainly in light of the continuous information and communication technology (ICT) development. In this context, the present paper sets out to present two important numerical electromagnetic (EM) methods, the method of moments (MOM) and our advanced transverse wave approach (A-TWA) for full-wave analysis of RF/MW structures. The computational complexity of these methods is evaluated. Two complex printed antennas working in the RF/MW range are selected and investigated. The EM problems that can be found in these circuits and that could not be solved analytically or by other numerical methods are discussed. The EM-validation of the studied structures using A-TWA and MOM is demonstrated and compared in the context of RF/MW applications. The obtained simulation results prove the efficiency and rapidity of our approach in comparison with the literature.

Mutual coupling studies between printed antennas had known some difficulties arising out of either physical phenomena or mainly the computational EM methods used for EM analysis. In this paper, the fast numerical electromagnetic (EM) method so-called Transverse Wave Approach (TWA) and its extended version are presented for EM field modeling of planar structures. Taking into account from benefits of the advanced TWA process, a new efficient technique is introduced to investigate the mutual coupling between antennas in periodic walls. The implementation of this approach with low complexity effort is demonstrated in the context of wireless applications and the obtained simulation results are found to be in good agreement with EM theory and literature.
