Keynote Speakers
Prof. Susumu Sasaki (JAXA, Japan)
Title:
Wireless Power Transmission Technologies for Solar Power Satellite
Abstract:
Solar Power Satellite (SPS) is an energy system which collects solar energy in space
and transmits it to the ground. It has been believed as a potential infrastructure to
resolve global environmental and energy problems for human beings. One of the most
critical technologies for the SPS is the wireless power transmission from the
geostationary orbit to the ground.
Microwave power transmission has been investigated and demonstrated for more than
40 years, but still requires further research regarding high-efficiency power
conversion and high-accuracy beam control for SPS application. The keynote speech
will address technological advances in the past, major challenges we are confronting,
and future prospects for the wireless power transmission in the long range from space
to the ground.
Biography:
Susumu Sasaki received the D.Sc. from the University of Tokyo in 1976.
He joined the Institute of Space and Aeronautical Science in 1975.
Since 2000, he has been a professor of the Institute of Space and
Astronautical Science (ISAS)/Japan Aerospace Exploration Agency (JAXA),
working in the field of space power systems.
Prof. Joungho Kim (KAIST, Korea)
Title:
Resonant Magnetic Field Technology for High Power and Enhanced Efficiency
Wireless Power Transfer
Abstract:
Recently, KAIST has introduced the novel on-line electric vehicle (OLEV), in which the
automotive vehicle constantly receive energy from the power lines embedded underneath
the surface of the road. OLEV has the reduced battery capacity to about 20 percent
compared to that of the conventional battery-powered electric vehicles, while it can
consequently minimize the weight and the price of the vehicle and power station. In
this paper, we have introduced OLEV and its wireless power transfer mechanism.
The suggested electromagnetic field design methods were successfully demonstrated
passive and active shield method to improve the power transfer efficiency and to suppress
the leakage magnetic flux lower than 62.5 mG.
Biography:
Dr. Joungho Kim received B.S. and M.S. degrees in electrical engineering from Seoul National
University, Seoul, Korea, in 1984 and 1986, respectively, and Ph.D degree in electrical
engineering from the University of Michigan, Ann Arbor, in 1993. In 1994, he joined Memory
Division of Samsung Electronics, where he was engaged in Gbit-scale DRAM design. In 1996,
he moved to KAIST (Korea Advanced Institute of Science and Technology).
He is currently a Professor at Electrical Engineering and Computer Science Department, and
the group director of Convergence Device and System Group.
Since joining KAIST, his research centers on EMC modeling, design, and measurement
methodologies of 3D IC, System-in-Package(SiP), multi-layer PCB, and wireless power transfer
technology. Especially, his major research topic is focused on chip-package co-design and
simulation for signal integrity, power integrity, ground integrity, timing integrity, and
radiated emission of 3D IC and SiP. He has successfully demonstrated low noise and high
performance designs of numerous SiP's for wireless communication applications such as ZigBee,
T-DMB, NFC, and UWB.
He was on a sabbatical leave during an academic year from 2001 to 2002 at Silicon Image Inc.,
Sunnyvale CA. He was responsible for low noise package designs for SATA, FC, HDMI, and Panel
Link SerDes devices. Recently, he started a new research on wireless power transfer technology
using magnetic field resonance. He has been one of the co-leaders in a national project, OLEV
(Online Electrical Vehicle), for EMI and EMF reduction design. The OLEV was selected as one of
the 50 Best Inventions in 2010 by Times Magazine.
Dr. Vijayalaxmi (University of Texas Health Science Center, USA)
Title:
Biological Effects in Mammalian Cells Exposed to Electromagnetic Fields
Abstract:
A multitude of devices emitting electromagnetic fields are used in medicine, industry and for
a variety of military purposes. During the last several decades, numerous researchers have
examined the effects of exposure of electromagnetic fields in mammalian cells. The potential
'adverse' effects of such exposures on the genetic material (DNA) are very important. Damage
in the DNA of somatic cells can lead to the development of cancer or cell death.
Changes in the DNA of germ cells can lead to mutations that can be transmitted to subsequent
generations. Hence, several investigators have used a variety of laboratory techniques to test
for the induction of genetic damage following
in vitro and in vivo exposure of animal and human cells to electromagnetic fields.
The overall data will be presented and discussed in connection with human health.
Biography:
Dr. Vijayalaxmi is at the Department of Radiology, University of Texas Health Science Center
in San Antonio, Texas, USA. After completing her Ph.D in Southern India, she received a post-
doctoral fellowship from the World Health Organization for advanced training in cytogenetics
in Scotland and Holland. She accepted the position of a Scientist in British Medical Research
Council's Human Genetics Unit in Scotland and continued to work there for the next 10 years.
Then, she moved to Switzerland for 2 years to work at the Swiss Federal Radiation Research
Institute. Since 1994 she is focusing her research on the biological effects of non-ionizing
radiation in Texas. She has published >85 papers in peer-reviewed scientific journals; four
of them were in prestigious journals, three in Nature (London) and one in Science.
