Abstract
In the rapidly evolving terahertz (THz) technology field, all‐dielectric metasurfaces (ADMs) have emerged as a significant driving force, potentially can transform various industries and scientific disciplines. This review offers a comprehensive and in‐depth examination of the underlying principles, materials, fabrication techniques, and state‐of‐the‐art design methods associated with THz ADMs, including the emerging role of artificial intelligence in their development. The diverse applications are delved into of these metasurfaces, such as high‐resolution imaging, advanced sensing, and the development of tunable devices, showcasing the versatility and promise of ADMs in the THz range. Furthermore, the significance of interdisciplinary collaboration is discussed and the integration of cutting‐edge technologies in pushing the boundaries of ADM‐based THz devices. As the field continues to grow and innovate, the applications and implications of all‐dielectric metasurfaces in the terahertz range are expected to become increasingly diverse, paving the way for transformative breakthroughs across various sectors.
