摘要

金属纳米膜的自组装是制造毫米至太赫兹行波管放大器的螺旋慢波结构的可行途径。这项工作协调了冷螺旋的三维模拟和束波相互作用的一维模型，以确定慢波结构的设计参数的有用范围。这些参数包括直径和节距。基于仿真结果，我们制作了具有微尺度直径和节距的螺旋原型。纳米膜的刚度和内嵌应力控制了螺旋的几何形状。

Design and Fabrication of Self-Assembled Metal Helices for Millimeter-through- THz Traveling Wave Tube Amplifiers

Self-assembly of metal nanomembranes is presented as a viable avenue to fabricate helical slow-wave structures for millimeter-through- THz traveling wave tube amplifiers. The work coordinates three-dimensional simulations of cold helices and one-dimensional models of beam-wave interaction to determine a useful range of design parameters for the slow-wave structures. These parameters include diameter and pitch. Based on the simulation results, we fabricate prototype helices with microscale diameter and pitch. The nanomembrane stiffness and the built-in stress control the geometry of the helices.
