“…This problem and some related issues will be addressed in Section III. An analogous argumentation is valid for ψ (2) and ψ (3) . Due to the specific form of (15) and (18), with a single multiplicative degree of freedom for each basis function f c1,n (its coefficient A c1,n ), ψ (1) is fully determined over the complete triangle, once its boundary value on c 1 is fixed, and so are ψ (2) for side c 2 and ψ (3) for c 3 .…”

“…However, our method uses the combination of three sets of expansion functions, which are, on their own, only sufficient to represent a prescribed boundary value on one of the sides, but altogether on the three sides. Although the introduction of two extra sets of waveguide modes is at first glance unnecessary, our method has the advantage that we can enforce ψ (1) to be zero at p 3 , in this way avoiding the exponential terms in (18) to become large (and analogously for ψ (2) and ψ (3) ). If, instead, (21) would be used, the exponential behavior of the parallel-plate waveguide modes in the direction perpendicular to c 1 would lead to ill-conditioning and completely inaccurate results.…”

“…The influence of the finite conductivity of the conductors and the associated frequency dependent skin effect losses and internal inductance (the so-called current crowding phenomenon) has received considerable attention in literature, see e.g. [2] and [3] and the many references in these papers. In [4] a single lossy line in the presence of a semiconducting substrate is analysed in the quasi-TM limit.…”

Abstract-This paper introduces a fast and accurate method to investigate the broadband inductive and resistive behavior of conductors with a non-rectangular cross-section. The presented Iterative Combined Waveguide Modes (ICWM) algorithm leads to an expansion of the longitudinal electric field inside a triangle, using a combination of parallel-plate waveguide modes in three directions, each perpendicular to one of the triangle sides. This expansion is used to calculate the triangle's Dirichlet to Neumann boundary operator. Subsequently, any polygonal conductor can be modeled as a combination of triangles. The method is especially useful to investigate current crowding effects near sharp conductor corners. In a number of numerical examples, the accuracy of the ICWM algorithm is investigated, and the method is applied to some polygonal conductor configurations.Index Terms-Dirichlet to Neumann operator, iterative combined waveguide modes algorithm, triangle, polygonal conductor, skin effect, quasi-TM approximations.

“…However, (L p , R)PEEC model yields incorrect predictions of damping or losses that occur at high frequencies or for obviously capacitive dominant systems. Anyway, variants of solvers for 2 exist so as to focus more specifically on one or other interesting physical phenomena intrinsic to the problem; for more details on existing applications see [11] [16] and [17].…”

Abstract-Induction machine is widely used in industrial applications, and currently numerous researches deals with its on line monitoring. A great on line monitoring would provide fault diagnosis, optimal use and quality management. However, diagnosis is, until today, mainly based on vibration analysis and/or motor current signature analysis (weel known as MCSA). This paper presents a new approach in the whole electrical drive diagnosis thought original measurements. The first part shows that the measures of the electromagnetic field emitted on the DC bus bar of the inverter can provide a relevant signature for the spectral analysis of the power drive. The second part deals with the in sight simulation prospectives, through the widely spread Partial Element Equivalent Circuit (PEEC) modelling of the surfacic conductor structures.

“…It is clear that accurate electromagnetic modeling tools need to correctly account for the redistribution of the conductor current. This has, of course, been recognized by many authors and numerous publications address this so-called current crowding problem, see e.g., [3]- [6]. We would especially like to draw the attention of the reader to [6].…”

Abstract-An important issue in high-frequency signal integrity prediction is the modeling of the skin effect of thick conductors. A new differential surface admittance concept is put forward allowing to replace the conductor by equivalent electric surface currents and to replace the material of the conductor by the material of the background medium the conductor is embedded in. This new concept is studied in detail for the two-dimensional TM case starting from the Dirichlet eigenfunctions of the cross section. Detailed expressions are derived for the important practical case of a rectangular cross section. Next, the differential surface admittance operator is exploited to determine the resistance and inductance matrices of a set of multiconductor lines. A first set of numerical results provides the reader with some insight into the behavior of the surface admittance matrix. A second set of results demonstrates the correctness and versatility of the new approach to determine inductance and resistance matrices.
