      JSPS Ikushi Prize
      In 2009, JSPS received an endowment from His Majesty the Emperor Emeritus Akihito on the 20th year of his reign. Amidst a severe economic environment in Japanese society, His Majesty’s desire was to encourage and support young scientists who are working diligently to advance their studies and research. In deference to his wishes, JSPS established the JSPS Ikushi Prize program and placed it into operation in FY 2010. It functions to formally recognize outstanding doctoral students who can be expected to contribute to Japan’s future scientific advancement.

      Optical mode demultiplexing based on the universal optical circuit.
      The technology of spatial mode-division multiplexing is garnering significant attention as a next-generation solution to support the rapidly growing demand for optical communications. This innovative technology has the potential to multiply the transmission capacity per optical fiber by dozens of times or more, enabling ultra-high-capacity transmission of 10 petabits per second. However, it also leads to significant power consumption and delay at the receiving end. In this research, we fabricated a "universal optical circuit" as a compact semiconductor chip that can replace processing on the receiver side simply by allowing light to pass through it, and aimed to create a high-capacity optical communication system with ultra-low power consumption. We have successfully achieved a compact and error tolerant optical circuit by implementing a unique method of multi-plane lightwave conversion on a semiconductor chip of a few millimeters square. Through actual transmission experiments of large-capacity mode-multiplexed signals using this device, we succeeded in mode decoding in the optical domain, making a significant contribution to the realization of low-power and scalable optical communication systems.

      <Your impression & future plan >
      We, the co-authors of Crane, are all very proud of this award. This project originated from the Mitou Project by Suto and Tanimichi, which was then extended as a research outcome. This work was on the design software of origami products with functions of simulating the origami, finding a new shape under design constraints, and generating the thickened structure for fabriaction of objects. The proposed software is publicly available and open-source, and thus we believe it will be leveraged in industry as well as in research fields. For the future, we will continue to publish succeeding projects on computational design and fabrication of origami-related products.

      WISS 2022 Best Paper Award

      <About awarded research(activity)>
      Wearable devices with small battery capacity are difficult to use for long time and have limited functions. Although a cloth-type wireless charger has the potential to stably power up functional wearable devices in the use, the electromagnetic field exposure in the body limits the power transmission amount, and the high loss of conductive yarns results in low power transfer efficiency. Therefore, we first improved a meander coil that we previously developed for wireless communication to efficiently power up the devices near the body surface while suppressing electromagnetic field exposure. Then, by using flexible liquid metal wires, we realized a safe and efficient wireless charging system capable of supplying 2.5 W of power with an efficiency of about 40%.

      <Your impression & future plan >
      I am very honored to receive this award. I would like to thank all of my collaborators who have worked with me on this challenging research and who have supported me in my research life. I hope this paper will contribute to the future development of wireless charging.

      Title: The Electromagnetic User Interface for 2D Wireless Power Transfer
      Wireless power transfer is getting attention for charging mobile devices such as smartphones. However, for wireless power transfer, unexpected misalignment will cause malfunctions, and this is thought to be one of the reasons it is not widely used. In this research, we propose a concept of a novel wireless power transfer system with force feedback that allows users to recognize intuitively that the mobile devices are being charged, even though the wireless power transfer uses an invisible electromagnetic field. We’ve been designing a system that applies a force (electromagnetic force) to the mobile device with an electromagnet array for moving the device, preventing malfunctions in the wireless power transfer, and having the user feel as if the device were connected to a cable.

    • Discovery of Giant Odd-Parity Magnetoresistance in Nonmagnetic/Ferromagnetic Semiconductor Heterostructures -Unique Electronic Transport Phenomenon due to "Symmetry Breaking" in Materials, a Possibility for Next-Generation Quantum Devices The research has been carried out by graduate student Kosuke Takiguchi, Associate Professor Le Duc Anh, graduate student Harunori Shiratani, and Professor Masaaki Tanaka of Department of Electrical Engineering and Information Systems, graduate student Ryota Fukuzawa and Professor Takuji Takahashi of Institute of Industrial Science, and Lecturer Takahiro Chiba of Fukushima National College of Technology. They fabricated bilayer heterostructure consisting of a nonmagnetic semiconductor (InAs) and a ferromagnetic semiconductor (GaFeSb). The research group has discovered a new electronic transport phenomenon that exhibits giant odd-parity magnetoresistance. The results were published online in Nature Communications on Nov.9, 2022.
      In ordinary materials, the change in electrical resistance (magnetoresistance effect) when a magnetic field is applied is exactly the same when the direction of the magnetic field is reversed. However, in the InAs/(Ga,Fe)Sb semiconductor heterostructures fabricated by the research group, giant odd-parity magnetoresistance (OMR) was discovered, in which the electrical resistance changes by 27% when the external magnetic field direction is reversed. This new OMR occurs in a one-dimensional conduction channel formed on the side edges of a nonmagnetic semiconductor layer, and it is caused by (1) "spatial inversion symmetry breaking" due to the surface potential of the side edge and (2) "time reversal symmetry breaking" due to magnetic proximity effect from the adjacent ferromagnetic semiconductor (Ga,Fe)Sb. This phenomenon is significant because the giant electromagnetic response due to symmetry breaking appeared in semiconductor heterostructures, which are compatible with electronics, and is expected to be used in next-generation spintronics such as highly sensitive magnetic-field sensors. The research results were published online in Nature Communications on November 9, 2022.

      <Your impression & future plan>
      Speech assessment technologies generally require clean speech, which is often difficult to obtain in a classroom. With a throat microphone, which detects not air particle vibrations but vibrations of the skin of the throat, only the target speaker’s voices can be recorded even with many surrounding learners. However, speech signals detected with a throat microphone are inevitably muffled. In this study, they are converted back to their clean and clear voices with DNN-based voice conversion techniques. As future work, further improvements of conversion performance will be needed.

      This research aims at the safe autonomy of planetary exploration robots. Safe autonomy is required for planetary exploration robots because it takes a long communication delay time. However, due to various constraints, highly accurate localization and terrain classification are difficult. Therefore, this paper proposed a new chance-constrained path planning method that considers the probability of incorrect localization and classification.

      "Isotropization of complex-valued reservoir computing on 2-D dynamical systems"
      Reservoir computing (RC), which achieves highspeed learning through a reservoir layer with recurrent nonlinear mapping to a high dimensional space, has been used for prediction and estimation of sequential data. To deal with complex amplitude data such as synthetic aperture radar (SAR) data, RC has been extended to the complex domain, complex-valued reservoir computing (CVRC). In this paper, we analyze 2-D dynamical systems and examined the isotropic dynamics of CVRC. We show that CVRC preserves the periodicity of the input signal and has a high robustness to initial values compared to non-isotropic real-valued RC (RVRC).
