ABSTRACT The Chromebook is a new, faster computer. It
starts in
seconds, and offers thousands of apps, including Web applications and
Android
apps. The Chrome OS operating system is automatically updated to ensure
the
computer remains secure and gets better over time. The Chrome OS
hardware team
makes Chromebook reference designs and develops new technologies for
them. The
team was heavily involved in the USB-C development and Google
was an early
adopter in laptops, tablets and phones. The USB-C connector is used to
provide up to 100W of power, high speed signals for data and
video, and
low speed signals for configuration. It therefore presents many SI, PI
and EMC
challenges. Starting from a system view of USB-C the presentation will
introduce some of the research done by the Google Signal Integrity and
Power
teams as they implemented it in devices. It will conclude with some
forward-looking
speculation on SI tools.

Time reversal may strike us
as a frivolous idea since we are unable to reverse the flow of time in
our universe.
However, our computational models of the laws of physics –
notably our models
of wave propagation – empower us to commute freely between
virtual past and
virtual future, and thus to interchange cause and effect. This
capability has
opened new frontiers in acoustic and electromagnetic wave engineering.
Over the
past twenty-five years, scientists and engineers have developed novel
concepts
that exploit the time symmetry of the wave equation and the resulting
ability
to reverse causality in the virtual realm. The talk will explore the
features
and challenges of computational time reversal, demonstrate the
methodology by
means of live simulation examples, and discuss its applications in
real-world
engineering, notably in imaging, remote sensing, EMC, and
electromagnetic field
structure synthesis.

ABSTRACT In electromagnetic compatibility, reside
some of the most complicated electromagnetic analysis problems. In
designing
highly complex electromagnetic systems, some of the side effects of
coupling,
radiation, and interference are unintended.
The challenge in EMC research is the mitigation of
these unwanted side
effects. These side effects generally give rise to the deterioration of
the
performance or even failure of a system. Given symptoms of degraded performance,
an EMC engineer is tasked to identify the root causes and find remedies. Hence, an EMC engineer to
a dysfunctional
electrical system is very much like a doctor to a malaise human body. To help EMC engineers identify the
root-cause of the symptoms, it is best to provide EMC engineers with as
much
data as possible. These data can be collected experimentally with
broadband or
time-domain techniques. Field scanning techniques have been used to
collect
these data, and they can be painfully slow. A prerogative is to design
systems
that can expedite the collection of these data. These data can be collected passively or
actively. In passive data collection, as little interference to the
operation
of the system is done. In active data collection, signals can be
injected into
the system to precipitate different responses from the system. Also, to
get as
much response from the system, data should be collected to be as close
to the
source of the noise as possible. Given the massive amount of data that
these experiments can generate, the onus is upon the theorists to
analyze them
and make sense of these data. There
are
a whole sleuth of methods that can be used to analyze these data. One
possible
candidate is the characteristic mode analysis.
Another possibility is the use of vector fitting
method, model order
reduction, and compact modeling to come up with simple models that can
explain
the character of the data collected.
Synthesis methods can also be used to construct
these simple models to
match the experimental data. Also,
many
methods developed in inverse scattering/source can be used to help
advance this
field. Analysis methods for EMC are generally
slow. Hence, pressing research to expedite these analysis methods is
needed. Fast
algorithms in both CEM and
inverse analysis are needed. To
expedite
the analyses, advancement in large scale computing such as massively
parallel
computing can be used. Moreover,
ideas
from recent advances in expert systems and machine learning can
transferred to
EMC to solve pressing difficult problems. BIOGRAPHY ![]() ![]()
Considering the trend of
wireless area network shrinkage in coverage to increase capacity and
speed,
Zhang proposed the concept of wireless chip area network (WCAN) in
2002. WCAN
uses wireless technology to overcome the bottleneck of wired technology
to
realize interconnects among circuit cores in a chip (Intra-chip) or
among
different chips in a module (Inter-chip). WCAN, as a new paradigm for
wireless
communications and RF microelectronics, has begun to receive
considerable
attention recently. This talk will provide an introduction to WCAN.
Emphasis
will be given to the fundamental research in the characterization of
chip-scale
radio channels for WCAN. It is shown that the guided waves dominate the
chip-scale radio propagation. This talk will also touch on some key
issues in
the design of WCAN using modern integrated circuit technology such as
coupling
mechanisms and effects between on-chip antenna and inductor or coplanar
waveguide.

engineering career in 1968 at the Air Force Weapons Laboratory (AFWL)
in
Albuquerque, New Mexico as an Air Force Officer.
He worked with the early high-altitude
electromagnetic pulse (HEMP) codes, which calculate the HEMP
environments on
the ground due to a nuclear burst at high altitudes.
From 1972 through 1975, he worked for
Mission Research Corporation (MRC) in Albuquerque, New Mexico and
subsequently
in Santa Barbara, California. He
worked
on a variety of EMP phenomenology, system assessment and protection
projects
dealing with nuclear bursts at all altitudes, and with different
military systems. After
consulting from 1975-1977, he joined JAYCOR in 1977 as a Division Vice
President, opening and managing the Santa Barbara office, he continued
his work
advancing the state of the art of all types of EMP phenomenology and
systems
applications. He led standardization efforts to define the
high-altitude EMP
environment waveforms for aircraft and other DoD applications. In addition he developed
the current
injection levels for time-urgent C4I systems (MIL-STD-188-125-1 and -2). In 1984, Dr. Radasky founded a new
company, Metatech Corporation, in Goleta, California
(Santa Barbara County) where he is President
and Managing Engineer. At Metatech, Dr. Radasky continued his EMP work
protecting military systems, but also began his work in protecting the
critical
infrastructures from a range of severe EM environments.
This included new work to determine the
effects of severe geomagnetic storms on power systems, the effects on
Intentional EMI (IEMI) on the critical infrastructures, and the
non-linear behavior
of grounding systems to high-level lightning strokes.
In addition, he has spent substantial efforts
volunteering his time for standardization bodies such as the IEC, the
IEEE and
Cigré to make high-power EM protection part of the
discipline of EMC. He
also contributed to the U.S. Congressional
EMP Commission work from 2001-2008 and in 2017, as a Senior Staff
member. Dr.
Radasky has most recently been involved in the development of
commercial
electromagnetic compatibility (EMC) standards with the International
Electrotechnical Commission (IEC) in Geneva, Switzerland to protect
commercial
systems from all types of electromagnetic threats, including those from
the
high-altitude electromagnetic pulse (HEMP) and high-power
electromagnetic (EM)
weapons, which create intentional electromagnetic interference (IEMI). He has served as Chairman
of SC 77C, “EMC:
High Power Transient Phenomena,” beginning when the
subcommittee was
established in 1992 until 2016. In October 2004, Dr. Radasky was
awarded the
Lord Kelvin Medal in Seoul, South Korea by the IEC for exceptional
service in
the development of international standards.
