WS2-1 Overview of Numerical Electromagnetic Codes for EMC and EMC Demos

The objective of this workshop is to clarify the differences, benefits and particular characteristics of the most used and known numerical electromagnetic codes focusing on EMC applications. There are numerous Computational Electromagnetic Modeling (CEM) techniques available. They can be classified as full wave techniques including the Method-of-Moments (MoM), Finite Difference Time Domain (FDTD) and its derivations such as Finite Integration Technique (FIT), Finite Element Method (FEM), Finite Element Boundary Integral (FEBI) and hybrid solvers or asymptotic high frequency techniques such as Uniform Theory of Diffraction (UTD), Shooting and Bouncing Ray (SBR) and Physical Optics (PO). However, with the use of CEM there arise many questions, for example, which CEM technique is the appropriate one to use?, when?, and for what problem?. There are also the added limitations using CEM, which include finite computer memory, therefore in this topic High Performance Computing (HPC) techniques are addressed including a detailed explanation of Graphics Processing Unit (GPU) acceleration, Message Passing Interface (MPI) technology, Domain Decomposition Method (DDM), Spectral Decomposition Method (SDM), distributed solving and multiprocessing and multithreading techniques. Time and frequency domain comparison are also going to be demystified and explained in details.
The chair will present the following hands-on demos:
-How to import a PCB geometry, setup the model and simulate radiated emissions and radiated immunity using FEBI.
-How to import an airplane geometry and run a lightning strike simulation using FEM Transient
-How to run a crosstalk analysis in a package on board system.
The final objective is to provide the attendees a comprehensive explanation and details of the most used CEM techniques for EMC, including the most recent advances in commercial and scientific codes so one can choose the most suitable numerical technique for its specific application.
