“…Microstrip couplers are part of many microwave circuits and components and their design is of interest. Researchers in the past used the geometry of the lines to develop a model for the even and odd mode impedances of the line and hence calculate the coupling coefficient of the microstrip line accordingly [10][11][12]. The theoretical foundations and the models predict very close proximity to the real experimental results that are obtained, however the complexity of equations make the design a difficult task unless an optimizing tool in a CAD program is used.…”

“…It should be noted that the long history of solving the Laplace and Helmholtz equations is marked by the development of many numerical methods which are useful in simulation of practical devices. Such methods include the finite difference technique, extrapolation [14], point-matching method [15], boundary element method [16], spectral-space domain method [17], finite element method [18][19][20], transverse modal analysis [21] and mode-matching method [22]. A numerical integral equation approach is used in [23] to explore plane-wave scattering from a nonplanar surface with a sinusoidal height profile for the case of the magnetic field parallel to the surface ridges (TM polarization).…”

The research described in this chapter analyses two-dimensional potential problems for the multi-body systems, transverse electromagnetic wave propagation along multi-conductor transmission lines and two-dimensional plane wave scattering by various arrays. All conductors may be of arbitrary cross-sections the only restriction on the system geometry is a smooth parameterization. These problems are mathematically modelled by Dirichlet boundary value problems for either the Laplace or the Helmholtz equation, with the classical integral representation of the solutions in the form of single-layer potential. The analytical-numerical algorithm presented here is based on the method of analytical regularization. The key idea behind this technique is an analytical transformation of the initial ill-posed integral equations to a well-conditioned Fredholm second kind matrix equation. The resulting system of infinite linear algebraic equations is effectively solved using the truncation method the solution of the truncated system converges to the solution of the infinite system with the guaranteed accuracy that only depends on the truncation number and thus may be pre-specified. The solution obtained is applied to the accurate analysis of -D electrostatic-and electrodynamic-field problems for multi-conductor systems with arbitrary profiled conductors. Examples of some conceptual shielded transmission lines incorporating various configurations of conductors and scattering problems for the arrays of thick strips establish the utility of our method and its reliability in various situations

“…Multiconductor systems have been examined in the literature with the Galerkin method [1], spectral domain method [2], parallel lines propagating TEM waves method [3], the method of moments [4], finite difference methods [5], Green's function approach [6,7], the on-surface measured equation on invariance method [8], the method of lines [5,9], and domain decomposition method [10]. There are different studies available treating modeling and simulation of a micro strip transmission line, such as analytical methods [11][12][13][14] and methods summarized as extrapolation [13], point-matching method [15], boundary element method [16], spectral-space domain method [17], finite element method [18][19][20], transverse modal analysis [21].…”

This paper aims to analyze communication characteristics of the high current low-voltage (LV) busbar systems in 1-50 MHz frequency range due to the fact that busbar as an integrated part of the overall Power Line Communications (PLC) channel, it is necessary to investigate its communication characteristics. Firstly, the modeling of a compact structure LV busbar system is described. Then, this system carried out by an Electromagnetic (EM) analysis simulation tool based on methods of moments (MoM). Channel characteristics are obtained based on scattering parameters (S parameters) for the unit length (3 m) busbars. Characteristic impedances (Zc) are obtained approximately 22 , 18 , 14 , 11.5 and 9.7 for different busbars that have 1000 A, 1250 A, 1600 A, 2000 A and 2250 A current levels, respectively. On the other hand, the busbar length is changed as 3 m, 6 m, 9m and 12 m. The resonance frequencies for these lengths are calculated 33 MHz, 16 MHz, 11 MHz and 8 MHz, respectively. The results are given both graphical and numerical forms.
