Join us for THREE very Special Events
at the 2015 IEEE Symposium on Electromagnetic Compatibility & Signal Integrity
Tuesday, March 17, 2015: 8:30 – 10:00am
Mission City Ballroom 1
Over the last century, electronics has so insinuated itself into the fabric of civilization that hardly any aspect of our lives is not dependent on it. This talk will present the history of three events that underscore the fragility of what we have built. We've been remarkably lucky so far, but perhaps we should have a strategy, too.
Starfish Prime answered the question of what detonating an H-bomb above ground might do to electronics. On 9 July 1962, the US exploded a 1.4-megaton thermonuclear device a few hundred miles above Johnston Atoll in the Pacific Ocean. The effects were much stronger and more varied than anticipated. Radio communications as far away as Australia and California were disrupted. EMP knocked out or otherwise caused to malfunction hundreds of traffic lights in Honolulu, as well as numerous garage-door openers and microwave telephone relays. Perhaps its most famous victim, however, was Telstar, the first active telecommunications relay satellite, which had the misfortune of launching a day after Starfish Prime. The large flux of high-energy electrons produced by Starfish rapidly degraded Telstar's electronics, and rendered the bird silent within four months.
Hazards of this scale are not all due to avoidable human action. In 1859, telegraphers were shocked -- figuratively and literally -- by dramatic and puzzling phenomena. Sparks jumped across the gaps of telegraph keys; links functioned even when batteries were disconnected; and messages were received that had not been sent. At the same time, brilliant auroral displays were visible at unusually low latitudes. The British amateur astronomer Richard Carrington connected these occurrences to a solar flare he'd observed on 1 September. Today we know that a huge coronal mass ejection (CME) from the sun was ultimately responsible for these effects. A reminder that dangerously powerful CMEs are by no means rare came in 1989. A large CME-induced geomagnetic storm hit Quebec on 9 March, causing a massive regional power blackout within 90 seconds. Had it been a Carrington-level event, the damage could have been as high as a trillion dollars. That risk remains unmitigated today.
Thomas H. Lee is an electrical engineering professor at Stanford University. In 1994 he founded the Stanford Microwave Integrated Circuits Laboratory. He has written and co-authored several books and papers, and recently concluded a tour of duty as the director of DARPA's Microsystems Technology Office.
Our panel discussions have been designed to provide an opportunity for attendees to hear several individuals knowledgeable about specific issues or topics present information and discuss personal views. Our intent is to help you further clarify and evaluate your positions regarding the subjects being discussed and increase your understanding of the positions of others.
The EMCSI 2015 committee has identified current matters relevant to various industries in EMC and SI and we have invited a group of panelists with specialized experience in each area. Our response from our experts has been extremely enthusiastic and we hope you are as eager to attend as we are to introduce this new event. Let's get some great dialogue started!

In the past, the disciplines of EMC, Signal Integrity (SI) and Power Integrity (PI) was separate and analysis was usually performed by completely different engineers. However, the time has already come where for most system designs these disciplines can not be separate and must be considered together. This panel will discuss how and why these areas need to be considered simultaneously and the dangers of not doing so.

As high speed interconnect data rate increases (up to 25Gbps and above beyond 25 Gb/s), the need for an accurate interconnect measurement is ever critical. However, there is a lack of standard practices on how to measure interconnect at high frequencies:
Most instruments (such as VNA, TDR/TDT) can make good measurements at the end of a coaxial cable. However, test fixtures need to be inserted between an instrument’s coaxial interface and the DUT (PCB, package, connector, cable, etc.). There are various de-embedding approaches already commercially available, however, the de-embedding algorithms are often proprietary, and verification of the accuracy of the computed S parameters is left to the user.
A poorly designed test-fixture can lead to inaccurate de-embedded S parameters. An IEEE standard is needed to specify the electrical requirements of a properly designed test fixture to achieve high quality de-embedding.
The quality of measured S parameter of DUT can vary widely. There is no IEEE standard to check and validate the quality of S parameters before they are distributed for use. This has created many complications for engineers who are constructing models for high speed interconnect analysis. An IEEE standard is needed to check S parameters quality right after they are obtained in lab measurement.
In this panel discussion, the panelists will share their thoughts on how to address the above challenges of ensuring the quality of measured data for high frequency interconnect at bandwidths up to 50GHz. This might include but not limit to: recommended design of test fixturing, methods and processes for ensuring the accuracy and consistency of measured data for broadband signals with frequency content up to 50GHz.
ESD in Data Centers
Chair: David Pommerenke, Missouri University of Science & Technology, Rolla, MO

Reliability is a core goal for data center operations. Energy saving can be achieved by allowing a higher range of humidity and temperature within the data center. However, at low humidity the risk for ESD inflicted damage or upsets increases. The panel discussion will present material that analyzes the risk of upset or damage as a function of humidity for data centers and shows how flooring and foot wear can control the risk. Further, it provides data on the charge voltage and probability distribution for ESD induced by walking and other ESD causing events, such as sitting up from a chair.
