Abstract — In recent past EMI/EMC issues have assess design issues before going to a test chamber,
greatly increased in complexity due to the indeed before even building a physical prototype.
proliferation of electronics in all walks of life. As a
result, it is no longer possible to rely exclusively on
traditional techniques and expect cost-effective and
accurate solutions. The application of CEM to
EMI/EMC engineering/modeling is an emerging area
of research and the subject of EMI modeling is
beginning to appear frequently in the technical
literature. Obtaining an appropriate method for
modeling is a challenging exercise for the engineer
because the CEM realm is flooded with techniques
such as FDTD, FEM, MoM, TLM, FVTD, etc.
Moreover, these methods are further refined
frequently and hybrid methods were developed as
they were applied to real world problems. The most
painful fact is that no single modeling technique will
be the most effective and accurate for every possible
problem. So the EMI/EMC modeler is compelled to
follow a “right technique for the right job” approach. Figure 1 Figure_Name
