Copper Backplane Power Loss in an
Age of Increasing Data Rate Demand

With the recent explosion of online streaming services and continuing demand on bandwidth data rates there is a need for more accurate modeling of losses due to the propagating medium, periodic structures and rough surfaces.  For example, the IEEE 802.3 working group has several past, active, and evolving standards for copper backplane design:

·       In 2007 the IEEE created backplane standard (IEEE 802.3ap) for 1Gb/s & 10Gb/s,

·       In 2010  the IEEE created the standard (IEEE 802.3ba) for 40Gb/s, and

·       In 2014 it created a 4-lane (IEEE 802.3bj) standard for 100Gb/s.

This explosion in data rates from 1 Gb/s to 100 Gb/s has made the power loss in copper a very important subject within the industry and research institutions. Copper bandwidth has been required to operate at ~ 500 MHz circa 2007 to 12.5 GHz circa 2014 and frequency demands will continue to increase in the future. Being able to reliably predict channel power loss associated with data rates is helping to define the hardware infrastructure required for streaming services and the internet of things.

This webinar will provide a review of the barriers to higher data rates brought about by electromagnetic interactions within copper conductor printed circuit boards. The webinar will also discuss how this research has been developed into commercially available electromagnetic field solvers.

Why Attend?
  • To obtain a brief history about the Policy that helped shape and create the Internet and fuel its growth
  • To understand the impact Copper Roughness Loss and its medium have on Wireless and Digital Communications along with the Internet
  • To see how ongoing research has been developed into simulation software to predict system behavior for the next generation of communication


    Paul G. Huray
Professor of Electrical Engineering
University of South Carolina

Paul G. Huray grew up in Oak Ridge, Tennessee and pursued undergraduate work in engineering physics at the University of Tennessee (UT).  His UT graduate research was carried out in the Physics Division at the Oak Ridge National Laboratory (ORNL), he did postdoctoral research at the University of North Carolina (UNC), and in 1982 he completed the Institute for Higher Education Management at Harvard.

Huray was assistant, associate and full professor of physics at UT, and his research was conducted in the ORNL Transuranium Research Laboratory where he and his students carried out magnetic studies on the elements Np, U, Am, Cm, Bk, Cf and Es.  He led the effort to create a center of excellence "The Science Alliance" between ORNL and UT.

 In 1984 Dr. Huray began work as a White House senior policy analyst for President Ronald Reagan’s Office of Science and Technology Policy where he chaired the Federal interagency committee on Computer Research and Applications that created the Internet.

In 1988 Dr. Huray became Senior Vice President for Research at the University of South Carolina (USC), and was a member of President Bush's Council of Advisors on Science and Technology panel on High Performance Computing and Communications, vice chairman of the international steering committee for Intelligent Manufacturing Systems for the U.S. Commerce Department and served on the Department of Energy's Basic Energy Sciences Advisory Committee.

Huray has published 120 articles and 5 books including Maxwell’s Equations and The Foundations of Signal Integrity.  He has directed the work of 30 graduate students, received external funding awards for over $250 million, given 350 invited talks, and testified 9 times before the U.S. Congress.  More recently, Huray has been professor of Electrical Engineering at USC and has worked with the Intel Corporation to develop Signal Integrity solutions to overcome barriers for high speed communications systems, especially those involving copper transmission lines.

   Steven G. Pytel, Ph.D.
Lead Electronics Product Manager

Dr. Steven Gary Pytel Jr. is currently employed with ANSYS, Inc., as the Lead Electronics Product Manager. He received a Doctor of Philosophy specializing in Signal Integrity from the University of South Carolina. Steve previously worked at Intel Corporation as a Senior Signal Integrity and Hardware Design Engineer where he helped design Blade, Telecom, and Enterprise servers. His current research interests include high speed serial signaling, power delivery network impact on memory busses, electro-thermal interactions for 3DIC packaging and hybrid electromagnetic field solvers. He has over 30 publications along with several invited papers and presentations. He has written an invited chapter on signal integrity simulation for Maxwell’s Equations: The Foundations of Signal Integrity authored by Paul G. Huray.
