General Information
Microwave technologies are being used mainly for the purpose of communication and remote sensing, which can
be found in our daily life. Considering the environmental problems of our Earth, we need to explore a new way of
life with innovative technologies, which is an urgent issue today. What can the microwave technologies do for the
future? One potential and attractive answer is to develop innovative microwave technologies for wireless power
transmission so as to reduce power transmission cost and battery-related problems. J. C. Maxwell suggested that a
radio wave is in the form of a power in the end of 19th century. N. Tesla carried out the first WPT experiment even
though he failed it in the early 20th century. W. Brown demonstrated the possibility of a wireless power
transmission via microwaves in 1960 s. Following these pioneering works, the Space Solar Power Satellite has
been a principal application platform to conduct subsequent microwave power transmission research. In 21st
century, we have exploited numerous applications which are suitable for the use of wireless power transmissions
such as ICs, LED as tiny power digital device, electric vehicle and plug-in hybrid car. There exist several types of
wireless power transmission including inductive power transmission, resonance power transmission, and power
transmission via microwaves. The wireless power transmission technology is an emerging and innovative
application of microwaves with many interesting features and characteristics. We can deploy a number of wireless
power transmission technologies for specifically targeted applications.
