光生等离子体栅扫描天线研究进展

摘要

The antenna scanning techniques of Milli-Meter Wave(MMW) and terahertz(THz) wave have attracted much attention in electromagnetic field. Photo-Induced Plasma Grating(PIPG) scanning antenna as a low cost and rapid scanning technology provides a new approach and idea for MMW and THz wave beam steering. In this paper, the recent progresses of the photo-induced plasma grating scanning antenna are reviewed, which covers the working principle, structure, efficiency as well as the pattern. The study significance and main challenges are also discussed and prospected. It is a hope that this review will give a guide for the research and applications of the photo-induced plasma grating antenna.%毫米波和太赫兹(THz)波天线扫描技术已经成为当前电磁领域研究的热点，光生等离子体栅(PIPG)扫描天线技术作为一种低成本的快速扫描技术为操控毫米波和 THz 波提供了新的方法和思路。本文将对 PIPG扫描天线的原理、结构、效率和方向图等主要研究进展做详细的论述，并且对 PIPG 扫描天线的研究意义和存在的主要问题进行讨论和展望，希望对 PIPG 扫描天线的研究和应用提供参考。
