Abstract

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.

可垂直打印的渐逝模式滤波器

这项工作提出了一种新的倏逝模式滤波器（EMF）拓扑结构，允许其有效的增材制造（AM）。当垂直打印时（即，沿着滤波器的传播轴），可以考虑避免出现不期望的支撑物的倒角脊。这种策略确保了精确的公差，降低了成本，还使EMF能够作为供应链的一部分进行单片制造。开发了一个电路模型来解释新脊的行为，并加快整个滤波器的设计。通过原型的制造和测量，对所提出的概念和方法进行了实验验证。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
