Workshop Program

Radio frequency plays an important role in the daily lives and social and economic activities of the people. In anticipation of the full-fledged IoT era, while the use of radio frequency in various fields is progressing, it is necessary to achieve an advanced wireless communication network that can provide appropriate communication speed, flexibility and reliability according to the usage situation.
For this reason, the Ministry of Internal Affairs and Communications promotes research and development of new wireless communication systems such as 5G, 4K, 8K, IoT and others that contribute to the effective use of radio frequency, accurately grasps the radio frequency usage situation and creates new innovation, We are implementing various efforts to secure the frequencies necessary for the Olympic and Paralympic Games. In this presentation, we will introduce the latest radio frequency administration.

Vehicle innovation by ICT is amazing. By 2020 vehicles with Advanced Driving Assist System and / or Automated / Autonomous Driving capability will be lunched into commercial market. These new capabilities will be achieved by powerful wirelesscommunications, huge processing powers, and rich memories together with 3D digital map, big-data and artificial intelligence. Why don't we use these new capabilities for a social new infrastructure, for an example, vehicles in the parking where vehicle's automated driving capability is not needed? VaaSI is proposed and discussed in this address.

The 5^th generation mobile communication system 5G is a next generation mobile communication system having features such as "ultra-high speed/large capacity", "large number of connections", "ultra-low latency" etc., which further developed the existing system. It is expected that 5G will be realized as an ICT base of the advanced information society at an early stage. In recent years, in Japan, activities related to research and development and international standardization of technologies and functions supporting 5G, such as radio access network technologies and others, are rapidly accelerating toward the actualization of 5G in 2020. From this fiscal year, the Ministry of Internal Affairs and Communications (MIC) "5G system trials" has been started, and many stakeholders in various utilization fields participate in the trials as well as those related to the mobile communications industry to create a new market through actualization of 5G.
In this session, following the introduction of the overview of 5G system trials by the MIC, each domestic mobile communication operator promoting the system trial will introduce the content and plan of each trial.

Aerospace research and development have become active globally in recent years. As the latest efforts of space development in Japan, this workshop introduces the following three.
First, the mission, development and inflight status of the JAXA's asteroid sample return mission "Hayabusa2" is presented. Some up-to-date interplanetary communication technologies aboard Hayabusa2 such as the Ka-band system and the DDOR (Delta Differential One-way Range）technique are also covered in this talk.
Nest, we will describe an overview of the ALMA (Atacama Large Millimeter/submillimeter Array) telescope including the latest observation results and the receiver technologies which enables the high sensitivity observations. We also present future upgrade plans and the current status of R&D such as a multi-beam receiver and ultra-wideband receiver.
Finally, micro satellites, which started as academic tools for space science and engineering, are evolving rapidly and playing important roles in recent new space business. In this presentation, progress in micro satellites and trends in new space business will be introduced.

In the era of significant change throughout society, passive circuits including microwave filters have played main role in wireless communication systems using radio waves. In next generation of wireless communication systems such as 5G, it is inevitable to raise operational frequency adding to demands for low loss characteristics and miniaturization of passive circuits.
In this session, required fundamentals and vital points for design, simulation and fabrication are described based on microwave planar filter. Moreover, cautious technical points to realize compact microwave filter in the case of higher frequency are introduced.

Metamaterials are artificial materials which are composed of small elements compared to the wavelength, and macroscopic constitutive parameters are manipulated and designed in order to discover new phenomena of wave propagation and to invent state-of-the-art functional circuits/devices. It has been more than 15 years since the concept first appeared. The research area is not limited to electromagnetic waves and recently metamaterials have been applied to acoustic, sound, water waves as well as quantum waves.
In this workshop, we will review original electromagnetic metamaterials and their applications, focusing on transformation electromagnetics, applications to low-profile antennas, meta-surfaces, absorbers, and terahertz devices. The recent progress with cutting edge technologies in the microwave region up to terahertz frequencies will be shown.
