EMC Society of Australia Workshop 2018

(Past Workshop)

Our annual workshop featured short and long presentations from National and International experts in industry and academia, as well as Industry Exhibitions.

The EMC Society of Australia (EMCSA) annual workshop was convened in Adelaide, 22nd to the 24th of May in 2018.

The workshop is done and dusted. The event was well received by exhibitors, delegates and speaker all proclaiming it a successful event.

The Technical Program days was organised into three sessions. The following describes what occurred during the workshop.

 

Day 1 – Tuesday 22nd.  

 

Dr Bob Scully got day 1 underway with a presentation on “EMC Requirements Tailored for Space Applications”.  This presentation provided an overview at system level; and, including some spectacular video demonstrating lightning and its impact on spacescaft before launch; and, lightning as viewed from space.  Bob was very generous with his time and extraordinary knowledge, he described the properties of materials used and how potential differences, both intentional and unintentional, were managed on a spacecraft.

Session 1 then proceeded with a presentation on RADHAZ Measurements by Emad Mansour.   Emad detailed RADHAZ measurements and instruments required.  He then went on to demonstrate, through three case studies, that performing RADHAZ measurements can sometimes require an innovative approach.

 

Stephen Philips followed next and was the last of session 1.  Stephen detailed the difficulties of calibrating flicker and harmonic compliance test equipment.   The process developed and used by EMC Technologies was described.   The process also satisfies traceability requirements of ISO 17025.

 

Greg Gallagher was the only speaker in session 2 and presented a system level case study of his experience of mitigating EMC risks from electrical and electronic systems on the Air Warfare Destroyer HMAS Hobart

 

The only speaker in session 3 was Zhong Chen who provided a presentation on “Challenges and Methods to Improve Accuracies in Antenna Calibrations and Site Qualification Measurements below 1GHz”.  Zhong explained the test antenna calibration methods used by ETS Lindgren and how such methods produce results with a measurement uncertainty (MU) in the region of ±1.5dB to ±2.0dB.  Although very acceptable for EMC testing these MUs are not suitable for site qualification testing where the site qualification requirement is ±4.0dB. Options with reduced MU, including calculable antennas, were then described.

Day 2- Wednesday 23rd 

 

Session 4 started with another presentation from Zhong Chen, this time on “Advances in the Design of Anechoic Chambers for Modern Military Vehicles”.  Zhong described the requirements for Military EMC Chambers and how absorber requirements are determined.  Zhong then detailed the transfer characteristic and power dissipation properties of absorber and how some critical parameters are measured.

Bob Scully returned to the lecturn and presented “Cable Design and Construction”.  This presentation first described mathematical models for capacitive and inducting cable to cable coupling.  Then went on to answer the age-old question “ground the shield at one end; or, both ends?”   There is no simple answer; the only response has to be “it depends”.   Session 5 continued soon after with Mike Hatfield explaining the reason why the reverberation immunity test method produces an immunity threshold result lower than the anechoic test method.  The reason for this difference was shown to be due to directivity properties of the Device Under Test.

The only speaker in Session 6 was Mahan Rudd who brought the technical presentations to a close.  Mahan detailed the capabilities and application of Altair EM simulation software.

 

A panel was then convened and all present explored the subject “What is the future of EMC?”.  An interesting discussion followed where everyone took advantage of the opportunity to learn from the experiences and opinions of senior panel members.

 

Certificates of Appreciation were then presented to all speakers and organising committee.

 

Tutorials – Thursday 24th 

 

Tutorials were added to the EMCSA Workshop to give delegates an opportunity to explore subjects in more detail; and, enjoy one-on-one tailored interaction with presenters.   The delegates that took advantage of this opportunity were very appreciative of the opportunity.   Five tutorials were conducted in three streams and were:

Tutorial 1    Reverberation Chambers – Theory and Practice – Mr Craig Denton & Mr Mike Hatfield

Tutorial 2    Fundamentals of Shielding – Dr Bob Scully

Tutorial 3    Getting the best from electric field probes for EMC Testing – Mr Zhong Chen

Tutorial 4    Estimating Radiofrequency Radiation Hazards from Inside an Information Vacuum – Dr Paul Kay and Kevin Goldsmith

Tutorial 5    Computer Simulation for Electromagnetics – Dr Franz Schlagenhaufer and James Buchan

 

Trade Show – Tuesday & Wednesday   

 

The EMCSA Workshop is one of the very few occasions where all Australians involved in EMC come together in one place.  Trade Tables have become an important asset for major equipment and service providers to the EMC community.

 

Plenty of time was allowed to enable participants at the workshop to interact with the exhibitors and there were useful transactions that occurred to exhibition days to warrant persisting with the exhibition for future events.
