IEICE English Webinar

About IEICE English Webinar

 As a part of overseas activities, IEICE has been dispatching Distinguished Lecturers since 2010. The purpose of this program is to share knowledge, expertise, and insights on the future direction of electronics, information, and communication technologies at events held by IEICE international sections. In the current situation where overseas travel is restricted, IEICE offers livestream and on-demand webinars by Distinguished Lecturers.

 Please contact our Membership Section member2 for details. If the international section is involved in the event you are planning to dispatch the lecturer, please contact to the section representative instead.

    Brainmorphic Computing Paradigm and Hardware

    Prof.Yoshihiko Horio (Tohoku University)

    In order to realize brain-specific computational schemes such as consciousness/subconsciousness, prediction, inference, memory, attention, self, etc., novel computational principle, architecture, and devices are required, which would be very different from those in von Neumann-type digital computers. This talk introduces the brainmorphic computing paradigm and its hardware architecture. In the brainmorphic computing paradigm, information processing is performed through imitating the anatomical and physiological structure and dynamics of the brain, which have been evolutionally developed. The latest knowledge from brain science, especially, on high-order brain specific functions coemerged from high-dimensional complex structure and neuro-dynamics, should be reflected in the brainmorphic computing paradigm. In addition, the bodily and environmental constraints are considered and utilized as embodiment in this computational paradigm. In order to implement the brainmorphic computing paradigm as hardware, physical and dynamical characteristics of the novel brain-type constituent devices, especially nonlinear analog circuits, and nanometer-scale materials and devices, should be naturally utilized. Our efforts on physical implementation of the brainmorphic computing hardware are illustrated; for example, spin-orbit torque devices for naturally realize neuronal and synaptic dynamics directly, and a chaotic neural network reservoir for computation through high-dimensional complex dynamics.

    Introduction to Bioelectromagnetics – Fundamentals and Applications

    Prof.Akimasa Hirata (Nagoya Institute of Technology)

    The human body whose electrical behavior depend on the frequency should be considered in the modern design of wireless devices which are used in proximity of the human body. However, the complexity of the modeling may depend not only on the frequency but also the individual variabilities, environmental factors, size of the devices and use scenarios. In this lecture, first, a discussion on modeling of the human in the electromagnetics for different cases is provided. Then, the effect of the human presence on the wireless devices including wireless communication terminals and wireless power transfer systems is explained considering typical exposures scenarios. The electromagnetic fields emitted from the electrostatic discharge is also discussed.

    MIMO and Smart Antenna with Single RF-Baseband Chain and Switching Antenna Array

    Prof.Makoto Taromaru (Fukuoka University)

    MIMO, diversity, or adaptive array antenna, so called “smart antenna,” is an effective technique by space-domain processing to enhance channel capacity or to mitigate multipath fading and interference. However, it is difficult to reduce its cost, circuit size, and power consumption because it needs one by one RF-to-baseband chain for each array element; large scale RF/baseband hardware is necessary especially for large number of antenna elements i.e., massive MIMO and so on. To solve this problem, fast periodical antenna switching or beam scanning techniques have been proposed, where we call them “switching antenna array”. Although these are very attractive since MIMO or digital beamforming can be done with a single analog RF/baseband chain, they cannot perfectly have the same properties as the conventional multi receiver/transmitter architecture due to antenna switching or sampling. In this talk, spurious response/emission, and SNR (signal-to-noise ratio) property of the switching antenna array, are theoretically analyzed, and BER: bit error rate performance is quantitatively evaluated.

    Technologies and Commercial Applications of Far Field Wireless Power Transfer

    Naoki Shinohara (Kyoto University)

    A far field Wireless Power Transfer (WPT) is one of innovative radio wave applications and is recently considered as one of game changing technologies based on radio wave. It had been studied historically with microwaves and its application has been narrow beam WPT in which the wireless power is transmitted from one transmitter to one receiver with high beam efficiency. Recently, the WPT is applied as wide beam WPT in which the wireless power is transmitted from one/multi transmitter(s) to one/multi receiver(s) with various radio waves like a wireless communication system. In this talk, I introduce basic theory and technology, recent innovative technologies, and commercial applications of the far field WPT in the world. It involves an antenna / beam forming technology and a circuit technology in a receiver. Additionally, I also introduce discussion status of new radio regulation for the far field WPT in Japan and in the world.

    Physical Reservoir Computing: Its Advantages and Significance

    Prof.Akira Hirose (The University of Tokyo)

    This talk focuses on reservoir computing and its physical realization in the AI & sensor-network era. First, we have a glance of the hardware history in artificial intelligence (AI) including logic architecture and neural networks. The key point in modern AI is emphasized, namely, pattern information representation and pattern information processing. We also present the basic idea and dynamics of reservoir computing by referring to deep learning and time-serial information processing. Then we look through various physical reservoir-computing ideas briefly to catch the variety of physics used in this area and also the key properties. In particular, we go into the details of reservoirs based on photonics and spin waves. The former has been studied for long, resulting in an accumulation of experiences. The latter is new and rich in nonlinearity, hysteresis, anisotropy and dispersion, which enhance the processing ability. Lastly, we discuss the prospects of reservoir computing in the near future society in the context of edge-computing as well as server use in the sensor-network society.

    Sub-Terahertz Transceivers in Silicon

    Prof.Minoru Fujishima (Hiroshima University)

    The 300GHz band is a frequency band recently identified for wireless communication and is attracting attention towards 6G.However, it is generally believed that as the frequency increases, the communication distance becomes shorter and the applications are limited. In this talk, the relationship between frequency and communication distance will be explained, and the possibility of a 299GHz transceiver using CMOS integrated circuits will be discussed.
