Abstract:
While the global commercialization of the fifth-generation (5G) wireless communications is gradually taking off, there is already significant interest in the next generation of wireless communications. 6G, scheduled to be launched in 2030, will provide a Tbps data rate, microsecond latency, and almost unlimited bandwidth to the connectivity of numerous mobile and intelligent networks. This ultrafast transmission speed is enabled by driving the carrier frequency up to terahertz (THz) bands for more spectrum resources. Antennas and metasurfaces are ubiquitous and indispensable components for generating and manipulating electromagnetic (EM) waves. This talk will share a few discoveries in THz antennas and metasurfaces from 300 GHz to 1 THz with various functionalities, such as polarization conversion, focusing, and 3-D scanning. The metasurfaces at 300 GHz are fabricated by 3-D printed technology, while the metasurfaces/antennas at 1 THz are manufactured by microfabrication technology for a better resolution. This talk will also introduce their applications in communications and imaging.
