The iNARTE Informer – October 2011

Thoughts on the IEEE EMCS 2011

The 2011 Long Beach Symposium was one of the better EMCS events in recent years. The organization was done well, the venue was attractive and all the attendees we spoke with were enjoying the week. Our congratulations go to the symposium committee and their team of tireless volunteers.Most exhibitors reported good booth traffic and seemed generally upbeat about the activity in the EMC/EMI markets. It did seem however those companies with a diversity of products were doing better than the narrowly focused organizations.

This year iNARTE offered our traditional EMC Certification examinations as well as our new EMC Design Engineer examination and our MIL STD EMC Specialist examination. The new programs did attract a lot of interest and all our literature was snapped up, but only one applicant stepped up to be examined in the new MIL STD discipline, and no one was ready yet for the Design Engineer certification examination.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part Two

Maxwell’s Equations are eloquently simple yet excruciatingly complex. Their first statement by James Clerk Maxwell in 1864 heralded the beginning of the age of radio and, one could argue, the age of modern electronics.

We are in the middle of our Grandfather period for the Master EMC Design Engineer certification, and there were a lot of applicants taking up this offer and gathering their references from the other EMCS attendees. So the iNARTE booth was a pretty busy place.

Examination papers are now ready for this new program. Don’t wait for the next EMC Symposium to get this valuable new credential. You can sign up for examination at any of our almost 200 Authorized Test Centers by registering at the iNARTE web site,

This Engineer level certificate is designed for the graduate or the relatively new design engineer that is planning to build a career in EMC Design

As an independent credentialing agency, operating within the guidelines of ISO 17024, iNARTE has to maintain separation between training and certification determination. However, we do recognize how important it could be for many Engineers to be exposed to tutorials and workshops on the certification subject matter prior to examination. Consequently we are always eager to work with training institutes offering relevant courses and who are willing to include our examinations as a part of their program.

Washington Laboratories Academy is just such an organization, and the iNARTE MIL STD EMC Specialist examination is offered as an option to all attending their MIL-STD 461F courses. It has also been agreed that our new EMC Design Engineer examinations will be available to attendees at their upcoming High-Speed Digital Design Series, presented by Robert Hanson. For more information on these combination training/certification opportunities, please visit


Working closely with the ESD Association, iNARTE has created a new short form examination that is now available to ESDA Certified Program Managers. The questions in the short form exam relate to subject matter that is not well represented in the regular ESDA certification examinations for Program Managers. Because iNARTE recognizes the value of the ESDA credential, successful candidates taking the short form exam will be awarded full iNARTE certification and the certificates issued will feature a special endorsement in ESDC Program Management.


Four months have now passed since iNARTE and RABQSA signed a formal affiliation Agreement. The intent of the affiliation is to merge the iNARTE operations into RABQSA within twelve months of that signing date, and this process is well underway, but without either party taking any actions that cannot be rescinded in the unlikely event that either Board of Directors decide that this merger is not in the best interests of their organization.

After the merger, iNARTE will continue with its certification programs and the iNARTE name, together with the RABQSA name, will continue as brands of the new organization.

At this time, one of the first actions of the affiliation has been to give RABQSA access to the iNARTE Authorized Test Centers so that any of our proctors may be asked to host a RABQSA certification examination in their region.

At the same time, iNARTE is reviewing several RABQSA initiatives that could be developed into classic iNARTE programs targeting the individual practitioners, while RABQSA continues to offer certification to auditors, inspectors and assessors.

iNARTE and RABQSA together make up the world’s largest personnel credentialing organization with approximately 15,000 certificate holders

The following event offers candidates a chance to take the iNARTE certification examinations without incurring proctoring fees.

IEEE PSES 2011 – San Diego, CA. iNARTE examinations on October 13th

Candidates can register in advance at the iNARTE web site ( to examine at this event for any of the programs that we offer. At the event, candidates can register until the day before the exam, but only for the discipline related to the event.favicon



Last month we asked:

The following figure shows closely arranged square parallel plates having a(m) in length on all sides. When the space between the plates has a relative dielectric constant of 4, and a separation distance of 2mm, what is the lowest resonance frequency between these plates?

(A) 300/a (MHz)
(B) 150/a (MHz)
(C) 75/a (MHz)
(D) 37.5/a (H)
The correct answer is: (C) 75/a (MHz)

This month’s question is:

A discrete inductor mounted on a printed-circuit board is modeled at low frequencies as a pure inductance. At higher frequencies, the lumped-element model is?

(A) A parallel resistance, inductance, and capacitance circuit
(B) Still a pure inductance
(C) A series resistance, inductance and capacitance circuit
(D) A pure resistance

began his career in electro-magnetics at Plessey Research Labs, designing “Stealth” materials for the British armed services. In 1973 he moved to the USA and established a new manufacturing plant for Plessey to provide these materials to the US Navy. In 1980 he joined the “Rayproof” organization to develop an RF Anechoic Test Chamber product line. As a result of acquisitions, Rayproof merged into Lindgren RF Enclosures, and later into ETS-Lindgren. Following a career spanning more than 40 years in the electromagnetic compatibility field, Brian Lawrence retired as Managing Director of ETS-Lindgren UK in 2006. Later that year he assumed the position of Executive Director for the National Association of Radio and Telecommunications Engineers, NARTE. Now renamed iNARTE, the Association has expanded its operations and is today an affiliate of RABQSA under the overall banner of the American Society for Quality, ASQ.
