This work presents a new topology of evanescent mode filter (EMF) that allows for its efficient additive manufacturing (AM). Chamfered ridges which avoid the appearance of undesired supports when printed vertically (i.e., along the propagation axis of the filter) are considered. This strategy ensures accurate tolerances, reduced cost and it also enables monolithic manufacturing of the EMF as part of a feed chain. A circuit model is developed to explain the behavior of the new ridges as well as to speed up the overall filter design. The proposed concept and methodology are validated experimentally through the manufacturing and measurement of a prototype.

可垂直打印的消失模式滤波器


这项工作提出了一种新的倏逝模式滤波器 (EMF) 拓扑，可实现高效的增材制造 (AM)。考虑了倒角脊，以避免在垂直打印时（即沿着滤波器的传播轴）出现不期望的支撑。该策略可确保精确的公差、降低成本，并且还可以将 EMF 作为馈送链的一部分进行整体制造。开发了一个电路模型来解释新脊的行为并加速整体滤波器设计。所提出的概念和方法通过原型的制造和测量进行了实验验证。
