11.    Concluding Remarks

This sixth scientific workshop was entitled "Radio Waves and Biologyh and was the first cosponsored workshop with the URSI-K group. A diverse range of applications from medical issue and standardizations were presented by the front-line researchers in the field, and there was a fruitful gathering of participants both from the medical application and communication fields. The topics included technical issues of radio waves on ubiquitous communication and medical treatment, radio waves and non-invasive biological measurements, political issues on measurement standardization and numerical techniques, and botanical measurements of fruits by radio waves. Intensive discussions on this field of radio wave applications were held with discerning questions, and the meeting was a big success.

10.    The steering committee meeting took place from 8:50 to 9:50 on Sept. 3rd, 2005

11.    Concluding Remarks

This workshop was entitled "Radio wave and compound device", and the radio wave application of the compound semiconductor transistor was presented especially. The relation between the person and the corporate strategy to spread the technology as a product is talked about besides a technical story of the device. Technology trend of high-voltage device and low-voltage device was told. And some of practical application for satellite was presented. The person who related to various processes of the device participated in the workshop. At the banquet, the relation between the device technology and the crystal production in the Yamanashi area became a topic and it was interesting.

11.    Concluding Remarks

This workshop has covered a wide range of topics from fundamentals to applications of microwave materials by active researchers in the field. Professor Awai has presented an intuitive explanation of physics and characteristics of microwave ferrimagnetic materials and Professor Hashimoto has also presented novel trends and examples of microwave absorber applications, which is quite interesting and informative for audience. A talk on a hot topic on physics and properties of left-handed materials has been given by myself in the rump session with more than one hour extension, resulting in precious and fruitful discussions. It is unfortunate that the first talk on microwave dielectric materials by Dr. Tamura has been canceled. By courtesy of Professors Awai and Zhang, a one day Biwako Lake tour program has been took place the next day with six attendees. It has gone smoothly through the day and has helped for exchanging information and mutual friendship.
