White Paper: State Of The Art In EM Software For Microwave Engineers

By Jan Van Hese, Jeannick Sercu, Davy Pissoort, and Hee-Soo Lee, Agilent Technologies, Inc.

The growing number and complexity of high frequency systems is leading to an increased need for electromagnetic (EM) simulation to accurately model larger portions of the system. There are several different technical approaches to EM simulation, and while no method is generally superior to the others, each one of them is aligned with one or more application areas. This article will discuss the three most established EM simulation technologies: method-of-moments (MoM), finite element method (FEM), and finite difference time domain (FDTD), linking the simulation technology to solving specific applications.
