Sho Masui of Advanced Technology Center Receives Two Presentation Awards

Sho Masui, a project research fellow at the Advanced Technology Center (ATC), received the Young Scientist Presentation Award at the 84th Japan Society of Applied Physics (JSAP) Autumn Meeting 2023 and the Electronics Society Student Award at the 2023 Society Conference of the Institute of Electronics, Information and Communication Engineers (IEICE). The Young Scientist Presentation Award is given to young members who have made excellent presentations at the Japan Society of Applied Physics Spring or Autumn Meetings that will contribute to the development of applied physics. The Electronics Society Student Award is given to students who have made outstanding presentations in the field of electronics at one of the conferences of the Institute of Electronics, Information and Communication Engineers.

【Young Scientist Presentation Award of the Japan Society of Applied Physics】

This award recognizes Masui’s presentation at the Spring Meeting in March where he presented proof-of-concept experiments on a novel microwave isolator that enables miniaturization. Isolators are components that control the direction of signals, prevent signal backflow, etc. Conventional isolators utilize magnetic materials, which in principle make it difficult to construct an isolator smaller than a few centimeters. As one of the solutions, a novel isolator that consists of frequency converters and phase delay components has been proposed. To demonstrate this principle, Masui conducted proof-of-principle experiments using commercially available frequency converters and superconducting ones and could confirm that they can operate as isolators. It is expected that the development of this isolator will contribute to not only the future of radio astronomy, but also to future quantum computers.

【Electronics Society Student Award of the Electronics Society of the Institute of Electronics, Information and Communication Engineers】

This award is in recognition of Masui’s presentation at the General Conference in March where he presented measurement results at cryogenic temperatures (around 4 kelvin) of the characteristics of a waveguide component used in mm-wave receivers. It is well known that the characteristics of waveguide components have a significant impact on receiver performance, especially as the receiver bandwidth becomes wider. Therefore, it is very important to measure them in the actual operation environment, such as at cryogenic temperatures. There are not many cases where these cold measurements have been performed accurately due to the influence of additional waveguides or other accessories that prevent heat or air penetration. Masui and his colleagues succeeded in obtaining very accurate measurement results by increasing the repeatability of the system and reducing the influence of multiple reflections using 2-tier calibrations. It is expected that the frequency characteristics obtained with high accuracy at the actual operating temperature will be important for further improvement of receiver performance and identification of issues. These newly developed techniques will be applied to the development of future receivers.
