CEM: Frequency Domain Techniques
Understanding and prediction of electromagnetic wave phenomena is now key to successful design for RF systems and EMC compliance. With modern desktop computing resources, frequency domain numerical electromagnetic techniques can significantly enhance understanding and provide reliable predictive capabilities across a wide range of problems, including those indicated below in the course subject material.
Key subjects covered
- Frequency domain integral (moment method) and differential (finite element) equation based techniques for predicting electromagnetic scattering from wire antennas/structures and conducting objects.
- Three dimensional modelling using moment method and finite element method of antennas in free space and over ground planes, including mutual coupling, antenna factors and use of antennas for EMC testing.
- Two-dimensional modelling using finite element method of conducting structures related to EMC.
Course scope
The course aims to give the delegate an appreciation of the uses and limitations of frequency domain computational techniques applied to EMC and RF problems. The module gives the delegate a thorough grounding in the methodology of these techniques from a fundamental standpoint, while giving a grasp of the practical applications. Simple problems are considered to give an understanding of how the choices made in designing the algorithms translate into the real strengths and limitations of the software. More complex EMC and RF antennas/structures and real EMC test environments are considered to give an insight into current and potential uses.
Who should attend
Engineers responsible for production or use of numerical modelling techniques. Engineers involved in EMC testing or EMC/RF antenna design who wish to gain an appreciation of the rôle of modelling within those areas.
