Short Course on EM modelling

Abstract:

The aim of the Short Course on electromagnetic modelling is to cover fundamental and practical issues of computer modelling with different numerical methods. The Short Course will present to its attendees an overview of modelling techniques. The focus will be given to two most popular discrete numerical methods: Finite Element Method and Finite Difference Time Domain method, addressing fundamentals, advantages, and basic causes of errors. The theoretical lectures will be supported with presentation of successful practical and industrial user cases on application of electromagnetic modelling, dedicated to variety of research areas, and hands-on sessions, delivering practical experience with two different electromagnetic solvers, QuickWave and InventSim, based on FDTD and FEM methods. Practical sessions will be focused on filters and antennas (including ultra-fast analysis of Body of Revolution problems, e.g. dual reflector antennas) design and analysis, with highlights concerned with other devices. The attendees will work with the solvers, preparing a predefined simulation scenarios, running the simulation, exploring basic and advanced solvers’ capabilities, and interpreting simulation results.

The Short Course attendees will be provided with a three-month trial licence of full-capability QuickWave software and one month evaluation licence of InventSim.
