Message from the Workshop Co-Chairs
On behalf of the IMWS-IWPT2011 Organizing Committee, I am pleased
to extend you a warm welcome and also an invitation to contribute to the
IMWS-IWPT2011. This workshop is the first IMS Workshop in Japan and the
first workshop in which we mainly focus on the wireless power transmission
(WPT) technologies and applications. We have plenary session, technical
sessions, and poster session on state-of-the-art technologies and
applications of the WPT presented by leading experts from around the world.
The WPT, especially microwave power transmission (MPT), has long technological history. There were a
lot of researches and experiments of the MPT in the world. Especially, after proposal of the Space
Solar Power Satellite (SPS) in 1968 which was biggest and most suitable MPT application, the MPT
researches walked along the SPS. Based on the technological history, we have some kinds of new WPT
technology like a resonant coupling and new applications suitable for the WPT in 21st century. 2011
is the first year of the innovative WPT technologies, systems and applications.
I hope you have a fruitful time in the IMWS-IWPT2011 and you find new knowledge of the MPT and the
WPT.

The microwave technology has been great progress in the field of wired
and wireless telecommunication systems and a sensor system. As the third
usage of the RF and microwave frequency, wireless power supply and energy
transmission and the related energy harvesting have been paid much attention.
The activities of the microwave power transmission (MPT) in Japan have been
activated by the SSPS project.
The most significant point of MPT is the effective use of the carrier energy
in the signal with various kinds of modulation. In addition, this concept can
be used in a radar system. In accordance with this stream, its application has
been extended into the communication and sensing systems. In this workshop, attractive active/passive
microwave components, antennas and systems for MWPT are demonstrated. Standing this view point,
we greatly expect the fruitful discussion.

Though I am a microwave engineer, some people do not think I am, because
I have plunged into the field of power transmission. The microwave technology
is so wide that it sometimes conceals the background of an engineer. In fact,
I was inspired by the microwave concepts to deal with the resonator and/or line
coupled WPT systems.
The development of WPT systems, however, has revealed the culture difference
between the microwave and power electronics societies. Considering the
importance of the present technology, we are expected to cooperate toward its
earliest practical application. The warm atmosphere of cooperation over the
world after the disaster in Japan will help improve the world-wide public welfare, not only the reconstruction
of Japan.
