Empowering terahertz sources with silicon antennas

该项目旨在制造用于高频太赫兹源的介质天线，即谐振隧道二极管。在最终用途的推动下，该项目预计将提供用于自由空间操作的高效率、高增益低轮廓腔体天线和用于导模操作的八木-UDA耦合器。硅将是这两种太赫兹结构实现最高效率的关键材料。有效媒介理论将实现性能、功能性和可积性，同时保持结构简单性以实现成本效益。预期的结果将取代几十年来昂贵的超半球透镜，用于5G以上的固定无线主干和短程透视雷达和成像中的未来太赫兹系统。

This Project aims to create dielectric antennas for high-frequency terahertz sources, i.e., resonant tunnelling diodes. Motivated by their end-use, the Project expects to deliver high-efficiency, high-gain low-profile cavity antennas for free-space operation and Yagi-Uda couplers for guided-mode operation. Silicon will be a key material for both types of terahertz structures to achieve highest efficiency. Effective medium theory will enable performance, functionality, and integrability, while maintaining structural simplicity for cost benefits. The expected outcomes will replace decades-old costly hyper-hemispherical lenses for future terahertz systems in fixed wireless backbone beyond 5G and short-range see-through radar and imaging.
