Terahertz Radiation – the Dawn of a New Information Era





Terahertz radiation;, 6G, Spintronic terahertz emitters, Antiferromagnets


This mini-review article explores the evolution of wireless communication technologies, emphasizing the crucial role played by advancements in information transfer over long distances with minimal errors. Tracing developments from submergible cables to the current 5G technology, the review discusses the potential of 6G, offering insights into the transformative applications it could enable, such as holographic real-time communication and autonomous transport infrastructure. Exploring the applications of Terahertz (THz) frequencies, the article presents the limitations of current wireless speeds and proposes solutions, including the use of spintronic terahertz emitters (STEs) and antiferromagnetic materials, concluding on the challenges and prospects of integrating these technologies into practical applications.
