3D打印金属管矩形波导（MPRWG）首次在WM-380（500-750 GHz）和WM-250（750 GHz-1.1 THz）波导频段进行了演示。新的RECILS增材制造技术提供的超高空间分辨率使这些原型MPRWG能够在如此高的频率下精确制造。这种使能技术避免了对昂贵的微加工资源的需求，从而为无源元件的低成本制造开辟了太赫兹频谱。
For the first time, 3D printed metal-pipe rectangular waveguides (MPRWGs) have been demonstrated in the WM-380 (500-750 GHz) and WM-250 (750 GHz-1.1 THz) waveguide bands. The ultra-high spatial resolution offered by the new RECILS additive manufacturing technology enables the precision fabrication of these prototype MPRWGs at such high frequencies. This enabling technology avoids the need for access to expensive microfabrication resources and, thus, opens up the terahertz spectrum to the low-cost manufacture of passive components.
