“…Once that this minimum is located, it is exploited as starting point of a Muller search routine in the complex plane. The final results of this procedure is the complex resonant frequency f re +jf im of the structure at hand [10,23]. The quality factor Q of the lossy resonator is easily computed as [12] …”

“…Figure 1 shows the layout of the SIW resonators taken in consideration in this work. Since the feeding techniques normally used in the applications of these devices do not excite the T E toẑ mode [10], only T M modes have been considered. Two sets of MLPNN networks, one for the circular geometry and the other one for the rectangular one, have been implemented in a MATLAB code.…”

“…The method provided also an easy way to analyze SIW resonators. In [10,11,23] the characteristics of SIW cavity have been proposed but losses were not taken into account and no results on quality factor were given. In [12] losses on the top and bottom plates and in the dielectric are included and results on quality factor are also given.…”

Abstract-In recent years, Artificial Neural networks (ANNs) have been intensively employed to build smart model of microwave devices. In this paper a characterization of lossy SIW resonators by means of Multilayer Perceptron Neural Networks (MLPNNs) on Graphics Processing Unit (GPU), is presented. Once properly selected and trained, a MLPNN can evaluate the lossy SIW resonator's resonant frequency f r and the pertaining quality factor Q at a shorter time than the full-wave rigorous model. In this way, fast parametric models of SIW structures to employ for the design and optimization of microwave devices, exploiting the computational power of GPUs, can be obtained.

“…The analysis of a SIW waveguide through the magnetic dyadic Green's function has been presented in Amendola et al, 2008). The application of the boundary conditions involves two systems of algebraic linear equations, one for the TM scattering and the other for the TE scattering, that can be expressed in a matrix form as Equation 1:…”

The design of Substrate Integrated Waveguide (SIW) resonators is usually a cumbersome process, especially due to the length "trial and error" procedure involved in this task. In this study Support Vector Regression Machines (SVRMs) are employed to compensate the modeling errors associated to the design of SIW rectangular cavity resonators. To validate the proposed approach, we have compared the design outputs provided by our method with the results provided by commercial full wave software. The comparison between our predictions and the full wave simulations validate the effectiveness of the proposed approach.

“…In this last case also, the presence of the metallic vias was included in the analysis solving the scattering problem. The method was also used to determine the characteristics of SIW resonators [17] and to analyze SIW based slot arrays [18]. In this paper we present the extension of the technique presented in [14], which treated only lossless case, to lossy structures.…”

Abstract-In this paper, a full-wave analysis technique of lossy substrate integrated waveguides, based on the dyadic Green's function of the parallel plate waveguide, is presented. The field inside the waveguide is expressed in terms of cylindrical vector wave-functions and the finite conductivity of the top and of the bottom plates, and of the metallic vias are taken into account. Losses into the dielectric substrate are also included. Coaxial ports are considered as sources and self and mutual admittances are evaluated. Cases of practical structure taken from literature are presented showing a very good agreement with the most used commercial software.
