EMC Metrology and Simulation

MESA Solutions, in collaboration with Altair FEKO, recently presented this new course in Australia.

Learning Outcomes

The foundation of this proposed 4-day course is based on the popular MESA Solutions “EMC Fundamentals for Laboratories and Industry” course. The proposed course covers fundamental EMC principles and illustrates how CEM can be used as a tool to visualise fields and currents in EMC-related problem solving.  The course is presented as a collaboration between instructors of Mesa Solutions and Altair.  After the course participants will:

  • Have working knowledge of methods of EMC coupling.
  • Have working knowledge of methods of shielding in problematic EMC environments.
  • Understand how to apply FEKO to modelling of typical EMC problems.

Course Structure

Day 1 to 3: Theory and Experiments, Supported by CEM Modelling

  • Common mode (CM) and differential mode (DM) coupling methods.
  • Transfer impedance of instruments and cables.
  • Seams and cable trays: Are full enclosures required?
  • Effect of shielding plates in coupling reduction.
  • 90% of EMC problems are cable related: experiments to demonstrate this.

Day 4: General Metrology & EMC

  • Spectrum analysers, network analysers and EMI receivers.
  • Current diversion techniques and grounding: Solutions to EMC issues?
  • Electric and magnetic field sensors and in-house calibration.
  • In-house pre-compliance testing & alternative EMC measurements.
  • What does all this mean for labs and industrial environments?

The course objective is to provide a deeper insight into EMC problems through measurement and computation. It will therefore be beneficial for participants to already command a basic understanding of electromagnetics and the use of CEM software at the start of the course. The course will be presented at suitable venues at the customer’s premises over 4 days. Attendees should anticipate 6 hours per day of active participation.
