## Abstract The present paper describes an unconditionally stable algorithm to integrate the equations of motion in time. The standard FEM displacement model is employed to perform space discretization, and the time‐marching process is carried out through an algorithm based on the Green's function

Abstract
We consider the problem of wave propagation for a 2‐D rectilinear optical waveguide which presents some perturbation. We construct a mathematical framework to study such a problem and prove the existence of a solution for the case of small imperfections. Our results are based on the knowledge of a Green's function for the rectilinear case. Copyright © 2008 John Wiley & Sons, Ltd.

## Abstract The harmonic and intermodulation distortions of both fully‐depleted (FD) and partially‐depleted (PD) silicon‐on‐insulator (SOI) MOSFETs are studied. The analysis is based on the recently developed integral function method and the results are compared to a third‐order Volterra model of t
