Abstract
Perfect vortex field as a new type of optical phenomenon, because of its unique orbital angular momentum and high spatial resolution and the high-profile, especially in areas such as communication, sensing, imaging and data storage show great potential applications.In recent years, with the progress of nanotechnology and metamaterial, the generation and modulation of perfect vortex beams using metasurfaces in the terahertz frequency band has become a research hotspot.This article will systematically review mechanism, perfect vortex beam discussed based on metal metasurface, all-dielectric metasurface and reconfigurable intelligent metasurface, and the medium ultra new progress of terahertz communication, and reveals its application prospect in the modern communication technology. At the same time, the current research challenges and future directions will also be discussed.
期刊介绍：
International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
