May 08, 2012: "Dipoles for Dummies (as well as all the rest of us without a PhD in electromagnetics)" by Henry W. Ott, Henry Ott Consultants
Abstract: An understanding of basic antenna theory would be helpful for all engineers, especially those involved in EMC. After all, if a product radiates (or is susceptible to RF energy) it is an antenna, even if you prefer to call it something else - such as a microprocessor, an IC, a PCB, a power cord, or an USB cable.
This presentation is a simple, insightful, and intuitive discussion of how a dipole antenna works, and how the operation is related to the commonmode radiation from a product. Attendees will end up with an understanding of dipole antenna theory, and know why dipole antenna theory is so important to EMC engineering. All of this is accomplishedthout using mathematics or writing a single equation.

April 10, 2012: "Reverberation Chamber Theory/Statistical Overview" by Prof. Charles F. Bunting, ECE Dept., Oklahoma State University; IEEE EMC Society Distinguished Lecturer
Abstract: To understand the application of reverberation chambers EMC engineers must delve into the scary world of statistics and applied random variables. This talk provides a discussion of the statistical electromagnetic environment in a reverberation chamber and the method by which the equipment under test can be tested to a given peak (or average) component (or total) field (or power) level with a definable uncertainty.
Bio: Chuck Bunting (S-1989, M-1994, SM-2011) was born in Virginia Beach, Virginia. He was employed at the Naval Aviation Depot in Norfolk, VA as an apprentice, an electronics mechanic, and an electronics measurement equipment mechanic from 1981-1989. He received his A.A.S. in Electronics Technology from Tidewater Community College in 1985, the B.S. degree in Engineering Technology with highest honors from Old Dominion University in 1989. He received the M.S. degree in Electrical Engineering from Virginia Polytechnic Institute and State University (Virginia Tech) in 1992. From 1991-1994 he held a Bradley Fellowship and a DuPont Fellowship and in 1994 he was awarded the Ph.D. in Electrical Engineering from Virginia Tech.
From 1994 to 2001 Dr. Bunting was an assistant/associate professor at Old Dominion University in the Department of Engineering Technology where he worked closely with NASA Langley Research Center on electromagnetic field penetration in aircraft structures and reverberation chamber simulation using finite element techniques.
In the Fall of 2001 he joined the faculty of Oklahoma State University as an associate professor and was promoted to full professor in August of 2011. His chief interests are engineering education, applied computational electromagnetics, statistical electromagnetics, electromagnetic characterization and application of reverberation chambers, and the analysis and development of near infrared tomography and microwave acoustic tomography for prostate cancer detection.

March 13, 2012: "Why does my design fail EMC? & How to fix it." by Jerry Meyerhoff, EMI/EMC Principal Consultant, JDM LABS LLC; IEEE EMC Society Distinguished Lecturer
Abstract: Overall EMC principles are introduced:
- 4 quadrants of mechanisms
- 3 elements of the actors
- 4 types of coupling
Case studies drawn from multiple designs are used to demonstrate the underlying EMC physics across the 4 quadrants for causes and cures. Analysis, measurement and creativity methods are highlighted. Narratives also present soft skills of teamwork & consulting persuasion. Solutions are generalized for applicability to multiple future designs.
Bio: Jerry Meyerhoff is currently the Principal of JDM LABS LLC, a consultancy which he started in 2009. He is devoted to assisting clients in optimizing designs for EMC, ElectroMagnetic Compatibility.
Previously Jerry was a Distinguished Member of the Technical Staff of Continental Automotive Systems, Deer Park, Illinois resulting from the acquisition of the former Motorola Automotive Group in 2006. He acted as a group-wide consultant in EMC design, serving multiple projects technologies and customers. Jerry's prior 36 years at Motorola involved hardware design and development applied to radios, RF and analog circuits and refining digital microprocessor hardware with increasing emphasis on EMC.
Jerry earned a BSEE, with emphasis on communications technology, from the University of Illinois at Chicago (UIC) in 1970. He immediately joined Motorola's Land Mobile Group. In 1971 he joined the US Army Reserve , was trained as a Fixed Station Transmitter Repairman 32C20 at Fort Monmouth, New Jersey serving the next 5 years in the 305th Psyop Bn. while pursuing his Motorola career. Jerry also took post graduate courses in RF design from IIT in Chicago.
At Motorola, Jerry lead design teams for the MICOM Solid State HF-SSB radio and then the MOCAT CB. He transitioned to the Technical Ladder as an individual contributor to FM and AM Stereo entertainment receivers for passenger automobiles. Ongoing he contributed to the development of many industrial and automotive control designs. In the Automotive Group, Jerry consulted on EMC design techniques across multiple electronics controls teams and Telematics product design groups. He is familiar with EMC lab measurement pitfalls and design problem resolution. He developed design guidelines, internal EMC lectures and acted as a trainer/coach to product development teams. He was a technical co-editor of Motorola's corporate Signal Integrity Technology Advisory Board newsletter.
