太赫兹芯片，速度72Gbps

Core Viewpoint - The sixth-generation wireless network (6G) is expected to achieve terabit-level transmission speeds using the terahertz frequency band, facilitated by advanced topological materials that enable multiple high-speed connections [2][3]. Group 1: Technology and Innovation - Researchers have developed an experimental device that achieves a data transmission rate of 72 gigabits per second while covering over 75% of the surrounding three-dimensional space [2]. - The new "leaky wave antenna" design allows for controlled leakage of terahertz radiation, ensuring smooth signal transmission without significant loss or distortion, thus enhancing bandwidth and data transfer rates [3]. - Compared to previous non-topological terahertz antennas, the new device increases coverage in three-dimensional space by 30 times and improves data transmission speed by approximately 275 times [3]. Group 2: Practical Applications - The new microchip can function as both a receiver and transmitter, allowing for bidirectional communication along the same path without interference [4]. - The antenna's radiation efficiency reaches between 90% and 100%, enabling the simultaneous transmission of uncompressed high-definition video while maintaining a high-speed wireless data link of 24 Gb/s [4]. - The envisioned TeraFi (terahertz Wi-Fi) technology is expected to provide speeds far exceeding current standards, making it suitable for environments requiring multiple reliable connections, such as vehicles, factories, and robotic platforms [4]. Group 3: Future Prospects - Terahertz technology presents significant opportunities in sensing applications, including terahertz radar (TeDAR), which can accurately detect objects, distances, and shapes, opening potential applications in autonomous systems, smart infrastructure, and industrial monitoring [4]. - The research team plans to integrate the antenna, radiation source, detector, and signal processing functions into a single chip to create a complete terahertz system, aiming to test networks of multiple collaborating devices [4].
