Abstract

We have numerically analyzed an electron beam -induced Airy beam-like terahertz (THz) radiation from graded metallic grating structures with graded groove spacing (GGS) based on a simplified particle-in-cell finite-difference time-domain method. Airy beam-like directional THz beams are obtained from GGSs designed to give appropriate phase delay in each scattered radiation from each grooves. Our findings may open the way for a development of novel THz radiation source based on the wide variety of metallic grating structures.
梯度金属光栅电子束诱导的类艾里光束太赫兹辐射
基于简化的细胞内粒子有限差分时域方法,对具有梯度凹槽间距的梯度金属光栅结构产生的电子束诱导的类艾里光束太赫兹(THz)辐射进行了数值分析。通过设计在每个沟槽的散射辐射中给予适当相位延迟的ggs,获得了艾里波束状定向太赫兹波束。我们的发现可能为基于各种金属光栅结构的新型太赫兹辐射源的开发开辟了道路。
