Studying Protoplanetary Disks to Understand Planet Formation
To form giant planets during protoplanetary disk lifetime,
small micron sized particles must grow rapidly to larger sizes. A full
understanding of that process requires a detailed characterization of the
radial and vertical structure of the gas-rich disks associated with forming
young stars. Multi-wavelengths observations of protoplanetary disks, for
example in the millimeter and near-infrared, allow to probe two widely
separated grain sizes that are differently affected by dust evolutionary
mechanisms. I will show that the modeling of multi-wavelength observations of
disks allows to identify high density regions. Those are favorable for grain
growth and allow to better understand the efficiency of planet formation in
protoplanetary disks.
About the Speaker
Marion received her MSc in Engineering (2013-2017) from the
Institut Supérieur de l'Aéronautique et de l'Espace (ISAE-Supaéro), Toulouse,
France, and MSc in Astrophysics (2016-2017) from Université Paul Sabatier,
Toulouse, France. September 2020, she finished her PhD at IPAG in Grenoble,
France on the study of the evolution of protoplanetary disks, using
multi-wavelength observations. Marion spent two years of her thesis in Chile
at the European Southern Observatory (ESO), where she learned to calibrate
and use complex ALMA observations. She is also familiar with scattered light
observation (with SPHERE or HST), and model both using radiative transfer.
She is now NASA Postdoctoral Fellow at JPL.
This event is free but registration is
required.

Antennas: From Ham Radio to Modern Communication Systems
6:30 PM PDT
at Hub101 and online
Speaker: Hanseung Lee
Register at: www.ieee-bv.org/meet/2023-05-com
Description
This seminar provides a comprehensive overview of basic
antenna theory and the introduction of various antenna types, from Ham Radio
to modern communication systems. The seminar will begin with an introduction
to basic antenna theory, including the principles of radiation and antenna
parameters. After the basics, the seminar will explore various types of
antennas and their respective properties and applications. The seminar also
covers advanced antenna concepts, antenna arrays and beamforming techniques.
Throughout the seminar, the focus is on practical applications and how
different types of antennas can be used to advance communication systems.

Laboratories in Malibu, CA, with over a decade of experience in electrical
engineering. He holds a B.S. from Korea University (2006), a M.Sc. from Seoul
National University (2008), and a Ph.D. from UCLA (2015). Dr. Lee specializes
in antenna design/analysis and RF circuit design/analysis, and has developed
cutting-edge technologies for clients such as Boeing, GM, and Apple, as well
as government programs. Prior to joining HRL Laboratories, Dr. Lee served as
a Senior Electrical Engineer at Skyworks Solutions Inc. from 2015 to 2019. Since
2019, he has been a key member of the HRL Laboratories team, utilizing his
skills and expertise to enhance the research and development initiatives of
the company. He was awarded the Asia-Pacific Microwave Conference (APMC) 2011
Prize and was also a finalist in the IMS 2014 student paper competition.

Lessons Learned from 60 Years of Flight Testing

Description
The Ohio University Avionics Engineering Center (AEC) is
somewhat unusual in that it is an academic research lab with its own fleet of
flight test aircraft. Over the decades the crews that fly these aircraft have
amassed a wealth of experience that can only be obtained ‘in the air.’ The
AEC’s DC-3 served as a flight-test platform for the world’s first commercial
GPS receiver back in the early 1980’s. Guidance, navigation and control
packages destined for installation in military unmanned aerial vehicles were
first put through their paces in the AEC’s ex-Soviet fighter-trainer, the
AeroVodochody L-29 Delfin. From flying synthetic vision displays up in
Juneau’s Gastineau channel to automatic dependent surveillance broadcast
(ADS-B) system flights down in the Gulf of Mexico, the AEC has been involved
in taking navigation research out of the classroom and lab and making the
systems work in the field and in the air. This lecture will cover a handful
of the many flight test stories in the AEC’s history. What kind of navigation
engineer do you need for a flight test with 6g turns? One that’s eager,
healthy and preferably has not eaten all day!
About the Speaker
Michael Braasch holds the Thomas Professorship in the Ohio University
School of Electrical Engineering and Computer Science and is a Principal
Investigator with the Ohio University Avionics Engineering Center
(AEC). He has been performing navigation system research for over 35
years and has served as a technical advisor both to the U.S. FAA and the
International Civil Aviation Organization (ICAO).
Mike is internationally recognized for his work in
characterizing the effects of GPS multipath. In addition, Mike’s
research in the application of phased-array techniques to differential GPS
ground reference stations laid the foundation for the development of the
first-generation prototype antennas for the FAA’s Ground-Based Augmentation
System (GBAS).
In the mid 1990s, Mike led the Ohio University research
group that pioneered the GPS software-defined receiver. He has also
conducted research in the design, development and flight-testing of advanced
display systems for general aviation aircraft. Mike has extensive
flight-testing experience with Ohio University’s fleet of research
aircraft. Mike’s more recent research has focused on gravity-modeling
considerations in high-integrity GNSS-aided inertial navigation systems.
Mike has served as a visiting scientist at the Delft
University of Technology in The Netherlands, was an Erskine Visiting Fellow
at the University of Christchurch, New Zealand and has lectured for NATO
AGARD in Russia, Turkey and Ukraine. He has also given invited talks in
Australia, Canada, China and France. Mike has served as an associate editor
for navigation and technical editor for navigation for the IEEE Transactions
on Aerospace and Electronic Systems and has also served as the associate
editor for navigation for the IEEE AESS SYSTEMS magazine. Since 2014 he
has served as the IEEE/AESS liaison to the ION/IEEE Position, Location and
Navigation Symposium (PLANS). Since 2017, he has served as the founding
Chair of the AESS Navigation Systems Panel. Mike has served on the AESS
Board of Governors since 2017 including service as VP-Conferences and VP-Technical
Operations. He is a licensed professional engineer in the State of Ohio

Description
Road transportation, which accounts for 22 percent of
greenhouse gas emissions, is undergoing a major transformation with the
advent of ridesharing, autonomous driving, and vehicle electrification.
Collectively these technologies, in conjunction with renewable sources of
electricity, have the potential to dramatically reduce the negative impact of
road transportation on the health of the planet. The successful convergence
of these technologies will require electric vehicles that are low cost and
fully autonomous. These attributes can be realized through dynamic wireless
charging. However, this will require wireless charging technology that is
well beyond current capabilities and opens new areas of research related to
power and transportation infrastructure. Using examples from research on
capacitive wireless charging (as opposed to the more common inductive
techniques), which leverage very high frequency power electronics, this talk
will highlight the opportunities and challenges in dynamic wireless charging
of electric vehicles.
