Electron beam excitation of coherent sub-terahertz radiation in periodic structures manufactured by 3D printing

[摘要] For the creation of novel coherent sub-THz sources excited by electron beams there is a requirement to manufacture intricate periodic structures to produce and radiate electromagnetic fields. The specification and the measured performance is reported of a periodic structure constructed by additive manufacturing and used successfully in an electron beam driven sub-THz radiation source. Additive manufacturing, or 3D printing, is promising to be quick and cost-effective for prototyping these periodic structures. (C) 2017 Elsevier B.V. All rights reserved.
