Publication & Awards

On 21st August 2023, Daisuke Kobuchi (D3/Department of Electrical Engineering and Information Systems) received URSI Young Scientist Award at URSI General Assembly and Scientific Symposium 2023.

Name of award and short explanation about the award:

URSI Young Scientist Award

This award is presented at the General Assemblies of URSI and at the URSI Atlantic Radio Science Conferences (AT-RASC) to recognize an international group of individuals who have made innovative contributions and discoveries in multidiscipline research related to electromagnetic fields and waves.

About awarded research:

Daisuke Kobuchi, Romain Siragusa, Yoshiaki Narusue, Arnaud Vena, and Etienne Perret, “Contactless Switching of a RF CBRAM Switch,” URSI General Assembly and Scientific Symposium (URSI GASS 2023), Sapporo, Japan, Aug. 2023.

Chipless RFID technology has been explored as a solution to low-cost individual identification systems. The CBRAM switch, a type of non-volatile switch, has been proposed as a means to embed information in chipless RFID tags. However, switching CBRAM requires direct contact between the probes and the switch electrodes for applying a DC voltage. This direct-contact method potentially causes short-circuiting of the tag antenna and degradation of switch electrodes. To address these challenges, we propose using a writer coil to induce multiple pulse voltages in the tag antenna, thereby switching the CBRAM switches without direct contact. We experimentally confirm the effectiveness of the proposed switching operation.

Your impression & future plan

I am very honored to receive this prestigious award. I would like to express my deepest gratitude to all of the collaborators who have worked with me on this research project.
