Abstract

The advancement of high-power miniature vacuum microelectronic devices in the millimeter-wave and terahertz ranges is very important for numerous applications in wireless high-speed communication, radar systems, electromagnetic sensing, spectroscopy, security, etc. Rapid prototyping of the pivotal electromagnetic components of these sources requires development of precise, fast, and cost-effective novel technologies. In this paper, we present the fabrication outcomes of millimeter-wave electrodynamic structures manufactured using a 3D printing via digital light processing technology, followed by metallization through magnetron sputtering. Rectangular waveguide sections for the V-band (50–75 GHz) and W-band (75–110 GHz) were fabricated, along with more intricate prototypes of periodic slow-wave structures, such as the vane-loaded waveguide structure widely used in traveling-wave tubes and backward-wave oscillators in the millimeter- and submillimeter-wave ranges. The measured cold-test electromagnetic characteristics, which demonstrate good agreement with numerical simulations, are reported.

利用增材技术快速成型毫米波电磁结构

毫米波和太赫兹范围内的大功率微型真空微电子器件的发展对于无线高速通信、雷达系统、电磁传感、光谱学、安全等领域的众多应用非常重要。这些源的关键电磁元件的快速原型设计需要开发精确、快速和具有成本效益的新技术。在本文中，我们介绍了使用数字光处理技术使用3D打印制造毫米波电动力结构的制造结果，然后通过磁控溅射进行金属化。制作了v波段（50-75 GHz）和w波段（75-110 GHz）的矩形波导截面，以及更复杂的周期性慢波结构原型，例如广泛用于行波管和毫米波和亚毫米波范围的后向波振荡器的叶片加载波导结构。实验结果与数值模拟结果吻合较好。
