Semi-Discrete Finite Element Method Analysis of Microstrip Structures

1991
Numerical modeling and characterization of passive components for Microwave and Millimeter-wave Integrated Circuit (MMIC) applications is an active area of research at the present time. The requirements of versatility, accuracy and computational efficiency have been met only partially by the existing numerical solutions. Therefore these issues continue

A semi-discrete method for analysis of tube-in-tube structures

Computers & Structures, 1994
Abstract A semi-discrete displacement-based variational method is proposed to analyse tube-in-tube structures. The framed tube is substituted by an equivalent continuous orthotropic tube. The framed tube and core wall are connected by continuous in-plane rigid floor slabs.

A semi‐discrete defect correction finite element method for unsteady incompressible magnetohydrodynamics equations

Mathematical Methods in the Applied Sciences, 2017
In this report, we give a semi‐discrete defect correction finite element method for the unsteady incompressible magnetohydrodynamics equations. The defect correction method is an iterative improvement technique for increasing the accuracy of a numerical solution without applying a grid refinement.

ANALYSIS OF THE SPACE SEMI-DISCRETIZED SUPG METHOD FOR TRANSIENT CONVECTION–DIFFUSION EQUATIONS

Mathematical Models and Methods in Applied Sciences, 2011
We consider space semi-discretization of the transient convection–diffusion equation using a Streamline Upwind Petrov–Galerkin (SUPG) finite element method. We show stability and convergence both for the standard SUPG formulation with elementwise evaluated Laplacian and for a weakly consistent formulation where the elementwise Laplacian is replaced by

Semi-discrete finite element method analysis of arbitrary microstrip elements-static solution

IEEE Transactions on Microwave Theory and Techniques, 1993
The semi-discrete finite-element method (FEM) is applied to solve the Poisson equation for a class of microstrip structures. This numerical technique is a variant of the conventional FEM. Its name stems from the fact that finite-element approximation is implemented only along two of the Cartesian coordinates, while the solution dependence on the third ...

Implicit-Explicit Multivalue Methods for semi-discretized PDEs

2014
Many practical problems in science and engineering are modeled by PDEs, whose space-discretization gives raise to large systems of ordinary differential equations (ODEs), characterized by a stiff part and a non-stiff one. A signifcant example is given by the discretization of advection-diffusion equations or advection-reaction problems with a stiff ...
