Simulation of MESFET device by streamline‐diffusion finite element methods

Xunlei Jiang

Uses a streamline‐diffusion finite element method, specially designed for semiconductor device models, to simulate silicon MESFET devices in two space dimensions. Considers the…

Towards a good characterization of spectrally correct finite element methods in electromagnetics

S. Caorsi, P. Fernandes, M. Raffetto

Spurious modes often appear in the computed spectrum when an electromagnetic eigenproblem is solved by the finite element method. Demonstrates that the inclusion condition, often…

Arclength continuation methods and applications to 2D drift‐diffusion semiconductor equations

A. El Boukili

Shows how a strongly non‐linear semiconductor equation can be solved via homotopy deformation methods combined with the arclength continuation procedures. The fundamental goal of…

Analysis of 3D scattering problems using finite elements and exact boundary conditions

A. Saadi, L. Pichon

Presents a new method to compute simultaneously the near and the far field in electromagnetic 3D scattering problems. In this approach a bounded spherical domain contains all the…

Direct dual finite element solution method for the determination of capacitance, conductance or inductance in static linear problems

D.M. Spink

Presents a direct solution method for the determination of the capacitance, conductance or inductance of static linear problems with the dual finite element method. The direct…

Comparison between finite element method and magnetic equivalent scheme to model an induction machine

P.M. Leplat, B. Lemaire‐Semail, S. Clenet, F. Piriou

Proposes to compare two models ‐ finite element method and “magnetic” equivalent scheme ‐ for numerical modelling of electromagnetic systems. Both these approaches coupled with…

Finite element analysis of saturation effects in a squirrel cage electrical machine

Andrzej Demenko, Lech Nowak

Presents a method for the finite element (FE) analysis of saturation effects in a squirrel‐ cage electrical machine. The proposed mathematical model includes the FE equations of…
