Scope of Symposium

Since the 1990s, science and technology of terahertz waves have made great progress, mostly focused on spectroscopy and sensing applications. In addition, the 5th generation (5G) service of wireless communications has been in operation from 2020, and along with this, the terahertz frequency region is attracting much attention as an important frequency band of future wireless information communication (Beyond 5G / 6G). The movement to develop new THz technologies, involving government and academia, is accelerating rapidly. With this background, in order to reaffirm the importance of terahertz technology and accelerate new technological and social developments, the Third International Symposium on Frontiers in THz Technology (FTT 2022) will be held in November 2022 in Fukui, Japan.

The First International Symposium on Frontiers in THz Technology (FTT 2012, Nara, Japan) was held in 2012, and the Second Symposium (FTT 2015, Hamamatsu, Japan) was held in 2015. After the International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2018, Nagoya, Japan), the Third Symposium was originally planned for 2021. However, due to the global spread of the COVID-19 pandemic, it was postponed by one year and successfully held in 2022 (FTT 2022, Fukui, Japan). Now, the Fourth Symposium is scheduled as FTT2025 to be held in Tokushima, Japan in 2025, at a time when the COVID-19 pandemic has fully subsided, and everyday life has returned to normal.

The topics covered in this international symposium are basic technologies, such as THz sources, detectors, components, materials, spectroscopy, and imaging, as well as biology / medicine, security, remote sensing. We comprehensively cover a wide range of research and development of terahertz science and technology, and practical technology, including the information and communication field. We will explore important fields and technologies associated with THz waves that could be the key to future social and industrial development, and also promote international exchanges regarding terahertz science and technology. The purpose is to provide an opportunity to create terahertz applied technologies that truly contribute to development of our society. In addition, we aim to provide young scientists with opportunities to make presentations at international conferences and interact with prominent overseas researchers.

We strongly wish many people participate to FTT 2025, and fruitful discussion on THz science and technologies will be made.
