An Introduction to FEKO
The purpose of this course is to train new FEKO users to make efficient use of the different user interfaces and to introduce a few of the various numerical methods in FEKO. Users will also learn to appreciate some of the strengths and weaknesses of different numerical methods in FEKO.
Upon completion of the course, trainees will:
- Be proficient in the user interface of FEKO.
- Be proficient in using the main numerical solver of FEKO (the MoM) and also know when and how to apply the higher frequency methods.
Proficiency in the use of FEKO is developed by letting all attendees work along with instructors on their own computers during interactive sessions. A typical short course consist of 2 days of instruction, but 3 days is recommended. The course is conducted as follows:
- Overview of FEKO's abilities.
- Introduction to the FEKO workflow and model setup and solving with FEKO.
- Model setup showing the versatility of CADFEKO and tools to help with efficient model setup.
- Introduction to high frequency methods.
Day 3 (Optional)
- Advanced model construction methods through application driven examples.
- Tools and tips to improve accuracy and reducing computational workload.
- Some time will be allocated for assistance with the solution of the customer's own problem.
The third day of training may be customized to focus on problems that are of interest to the customer's intended use of FEKO.
Short courses can be arranged on request at the customer's premises or prospective users can attend "open" short courses which are presented from time to time.
Course attendees should have a good understanding of basic EM radiation principles and the various concepts involved in antenna engineering, e.g. near field vs. far field radiation, S-parameters. This knowledge is assumed and will not be taught during the course. These concepts will be used to illustrate different aspects of EM modelling in FEKO.
No previous knowledge of computational EM is required and the required basic knowledge of mathematical models for Maxwell's equations will be introduced during the course.
FEKO short course instructors are also support engineers for the product and are highly experienced users of the software. In order to facilitate a learning environment where proper attention may be given to each course attendee an instructor-to-trainee ratio of no higher than 6:1 is adhered to.

EMC Metrology and Simulation
- EMC Metrology and Computation
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 EMSS-S.A. 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.
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.
The customer is required to provide a lab bench equipped with a signal generator, oscilloscope and soldering iron for every 5 trainees taking part in the course. This will allow a group of 5 attendees per bench to participate in physical experiments. Group size should be kept to 10 attendees or less.
A separate teaching venue with a digital overhead projector and white board is required.
CEM modelling sessions with FEKO require sufficient computers for the whole group to take an active part in model setup and manipulation. 1 computer per attendee is preferable and it is discouraged that more than 2 participants share a computer. Temporary FEKO licences will be issued to all participating computers for the duration of the course.
The course is jointly presented by instructors from Mesa Solutions and EMSS-S.A. The number of instructors will be determined by the size of the group of trainees.
Costs and Material Provided
Comprehensive notes and materials for experiment setup are provided.
Typical Course Dates and Timeline
