Development Status of Terahertz in China Detailed answer!
Development Status of Terahertz in Australia
In September 2024, an international team led by the University of Adelaide in Australia developed the first ultra-wideband integrated terahertz (THz) polarization multiplexer based on a substrate-free silicon platform and tested it in the Asia-Pacific THz J-band (220-330 GHz), which can be used for 6G and future communication technologies. The research findings were published in the latest issue of the journal "Laser & Photonics Reviews".
Terahertz prospects
The unique properties of terahertz (THz) have brought profound impacts to various fields such as communications (broadband communications), radar, electronic warfare, electromagnetic weapons, astronomy, medical imaging (label-free gene screening, cellular-level imaging), non-destructive testing, and security inspections (biochemical detection). Due to the high frequency of THz, it possesses a high spatial resolution; furthermore, its short pulses (in the picosecond range) result in a high temporal resolution.
Development Status of Terahertz in China
On October 28, 2016, news emerged that the 23rd Research Institute of China Aerospace Science and Industry Corporation had obtained China's first terahertz (THz) band outdoor Synthetic Aperture Radar (SAR) image, marking a breakthrough in key technologies for THz band radar imaging. Through this first THz band outdoor SAR image, key technical indicators and imaging algorithms were experimentally verified, laying a technical foundation for the engineering application of THz radar. However, due to limitations in the development level of high-power THz radiation sources, THz radar system imaging currently cannot fully meet practical application requirements.
