Workshop Program

Wireless power transfer (WPT) technologies are presently expected to commercial applications in the world. Especially, a microwave power transfer (MPT) technologies are presented in this session. The MPT can be applied for an energy harvesting from broadcasting or wireless communication microwaves, a WPT to multi-users like wireless communication systems, a WPT in closed waveguide, for example, 2-D sheet, and beamed WPT to a single user. In this session, various MPT applications are presented and a dream of next generation WPT like a Solar Power Satellite is introduced.

Wireless power transfer consists of three major parts, power source, power converter, and contactless power transfer components (antennas or transformers). Currently, researches on contactless power transfer components are very active. However, three components should be equally developed in order to realize high power wireless power transfer. In this workshop, there are two presentations from power electronics specialists and one presentation from circuit analysis specialist in order to introduce different approaches from the different viewpoints in order to understand wireless power transfer as a total system.

Electromagnetic (EM) simulators are necessary nowadays for simulation of high frequency circuits. Last year, analytically-solvable canonical problems (conducting/dielectric sphere, patch antenna with ideal excitation) were dealt with. This year, more realistic problems in measurement are focused. Circular and rectangular patch antennas fed by an SMA connector will be dealt with. Tips for good excitation modeling of realistic excitation structure will be discussed.

The rapid worldwide spread of personal wireless devices, for example a cell-phone, leads to penetration of informationcommunication technology into various scenes of social lives. To achieve the sustainable industries and society, “energy-informationvalue fusion network” supported by the information-communication technology has been globally constructing under concepts of Smart City/Community and open a door of new businesses related to RF and wireless technologies. For the purpose of getting a whole picture of the energy-information-value fusion network and having a view of such business, the cutting-edge engineers plainly explain the actual status of the typical standardizations, i.e., M2M, Wi-SUN, and Control System Security, and some business scenarios about them.
