“…Excitation is illustrated as a localized or a modal source, in discontinuity too [23]. The second is the method of moment (MoM) [21]. It associates the known test functions to a virtual source, injects a modal basis in environment operator, and projects test function on a modal basis to resolve the problem.…”

In previous modeling works, the waveguide radiation in the free space is modeled using an infinite flange in aperture plan. In this paper, we propose a new formulation to analyze the radiation of twin rectangular waveguides in free space. Our formulation consists firstly in simulating the free space as rectangular waveguide and seeking the appropriate dimensions that do not affect scattering parameters. In the second step, we use the symmetry principle to reduce the coupling problem to single guide radiating in the free space. Moreover, for more simplification, we consider a concentric discontinuity to solve this latter. This approach is based on moments method combined to the generalized equivalent circuit method (MoM-GEC) in order to reduce the number of unknown problems and alleviate their computation. Obtained numerical results are presented and discussed. A good agreement with literature is shown and the boundary conditions are verified.

“…On the surface Ω SU B=Sce , a magnetic excitation source (MES) or an electric excitation source (EES) can be disposed to ensure the mutual coupling between tangential electric fields respectively, and tangential magnetic fields on both sides of this surface as it expresses the imposition of a jump value on the surface of the electric respectively magnetic field [37,38]. They are represented by ideal generators as depicted in Figure 2.…”

Abstract-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 process is examined and the obtained simulation results are found to be in good agreement with literature.

“…The main idea is to combine the ordinary CG method to the Generalized Equivalent Circuit (GEC) modeling [13][14][15][16]. In this formulation, the impedance operator is used instead of the integro-differential operator [9] simplifying then the transition between spectral and spatial domains.…”

Abstract-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 various iris structures. Results computed using the new implementation of the conjugate gradient are similar to theoretical values. The field and current distribution are identical to the ones obtained with the moment method. Moreover, the memory resources required for storage are significantly reduced.
