Abstract

We generalize the theory of Smith-Purcell effect for a hollow electron beam moving above a metasurface. We find that radiation in coherent regime is sensitive to the electron distribution inside the beam and propose a noninvasive way to study hollow beams inner structure. Numerical estimates are made for the terahertz range.

来自超表面的空心电子束的相干史密斯-珀塞尔辐射。

我们推广了在超表面上运动的空心电子束的Smith-Purcell效应理论。我们发现相干态辐射对光束内部的电子分布很敏感，并提出了一种非侵入性研究空心光束内部结构的方法。对太赫兹范围进行了数值估计。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
