In the last decades these numerical me- ods that are used to calculate approximate solutions of Maxwell¿s equations have evolved from pure academic disciplines to powerful and user-friendly - gineering software tools. Meanwhile numerous commercial software packages exist that are widely used in the RF engineering community. Developments in thesoftwareaccompaniedbyprogressincomputertechnologyallownowadays many practical problems to be solved on standard PC systems. The text is written with di?erent groups of readers in mind. First it - dresses RF engineers who embark on numerical modeling using commercial ?eld solvers. Second it addresses graduate students taking practical courses in electromagnetic ?eld simulation. Both groups need a basic understanding of the mathematical background and both groups need a practical introduction tocommercialEMmodelingsoftwaretomaketheir?rstsimulationexperience a success. There are numerous books on the market that deal with mathematical details of di?erent numerical methods for the calculation of electromagnetic ?elds. For engineers who want to know what these methods can do for them and how to use the software tools, these theoretical books are too far away from daily work. On the other hand, there are tutorials and manuals that provide information on how to use speci?c software packages. These tutorials focusonthehandlingandspecialfeaturesofthesoftwareandmethodsapplied therein. However, the theoretical background and broader scope is generally neglected.
