Scientists at UNIST have developed a new technology that boosts terahertz (THz) electromagnetic waves by over 30,000 times, paving the way for a breakthrough in 6G communication frequencies. By combining this technology with AI based on physical models, the team has revolutionized the design and optimization of THz nano-resonators. The results of their research have been published in Nano Letters (domain: pubs.acs.org).
Under the leadership of Professor Hyong-Ryeol Park, the team collaborated with researchers from the University of Tennessee and Oak Ridge National Laboratory to optimize a THz nano-resonator for 6G communication using advanced optimization technology. By employing AI machine learning based on theoretical physics models, the researchers were able to effectively design nano-resonators on personal computers, reducing the time and resources required for this process.
The team conducted numerous experiments to evaluate the performance of the newly developed nano-resonator. The results were impressive, as the electric field generated by the THz nano-resonator exceeded ordinary electromagnetic waves by over 30,000 times, a significant improvement compared to previously described THz nano-resonators.
Traditionally, AI-based inverse design technology has focused on visible or infrared ranges, but its application in the frequency range of 6G communication posed a challenge due to its significantly smaller scale. To overcome these difficulties, scientists combined the THz nano-resonator with AI-based inverse design and theoretical physics models. This approach allowed for device optimization in less than 40 hours, even on personal computers.
The scientists believe that this breakthrough has implications beyond 6G communication as well. The optimized nano-resonator can be utilized in ultra-precise detectors, ultra-small molecule sensing sensors, and bolometer research. Furthermore, the methodology used in this study can be extended to various studies involving theoretical physics models of different wavelengths or structures.
According to Professor Park, understanding physical phenomena combined with AI technology is essential. While AI has its applications, grasping the fundamental physics is crucial for further advancement in various fields.
