A Sobolev gradient of a real-valued functional on a Hilbert space is a gradient of that
functional taken relative to an underlying Sobolev norm. This book shows how descent …

We consider a two-dimensional singularly perturbed convection–reaction–diffusion problem
that has discontinuities, along lines parallel to x-and y-axes, in the source term, as well as in …

Inadequate spatial mesh resolution for simulation of the time‐dependent Ginzburg–Landau
equations is shown to give rise to spurious solutions. Phenomenological studies to examine …

This paper presents an overview of active array antennas, system-level nonlinear effects in
such antennas, and their modeling and simulation techniques. Advantages of active array …

Purpose This paper aims to study boundary and interior layer phenomena in coupled
multiscale parabolic convection–diffusion interface problems and to present their efficient …

The quadrature modeling technique is nowadays widely used for the nonlinear simulation of
RF/microwave communication circuits and systems at the behavioral (system) level. It allows …

Purpose–The purpose of this paper is to extend the penalty concept to treat partial slip, free
surface, contact and related boundary conditions in viscous flow simulation …

A domain decomposition and parallel element-by-element (EBE) scheme is developed for
semiconductor device simulation modeled by the drift-diffusion (DD) equations. A classical …

We consider the use of adaptive mesh strategies for solution of problems exhibiting
boundary and interior layer solutions. As the presence of these layer structures suggests …

Schottky diodes realized on 4H–SiC n-type wafers with an epitaxial layer and a metal-oxide
overlap for electric field termination were studied. The oxide was grown by plasma …
