Demonstration of wideband metal mesh filters for submillimeter astrophysics using flexible printed circuits
摘要：
我们开发了一个宽带准光学带通滤波器，覆盖170-520 GHz的利用商业上可用的柔性印刷电路（FPC）制造技术的最新进展。我们设计并制作了一个三层堆叠的加载六边形网格金属网格使用铜图案的最宽线宽为$50~μ\mathrm{m}$的聚酰亚胺基板上。测量的频率通带的形状被成功地再现通过使用一组参数与制造的金属网的尺寸一致的数值模拟。基于FPC的金属网滤波器将以低成本和短的周转时间为毫米/亚毫米波准光学滤波器的按需开发提供新的途径。
英文摘要：
We developed a wideband quasi-optical band-pass filter covering 170-520 GHz by exploiting the recent advancements in commercially available flexible printed circuit (FPC) fabrication technologies. We designed and fabricated a three-layered stack of loaded hexagonal grid metal meshes using a copper pattern with a narrowest linewidth of $50~μ\mathrm{m}$ on a polyimide substrate. The measured frequency pass-band shape was successfully reproduced through a numerical simulation using a set of parameters consistent with the dimensions of the fabricated metal meshes. FPC-based metal mesh filters will provide a new pathway toward the on-demand development of millimeter/submillimeter-wave quasi-optical filters at low cost and with a short turnaround time.
