摘要

Additive manufacturing (AM) has proven to be a very interesting technology for a wide range of applications. In this paper, a stereolithography (SLA) 3-D printer has been used for the manufacturing of a new class of filters whose resonators consist of two mushroom-shaped posts transversely placed in a cavity. Each resonator implements a transverse doublet able to produce two poles and two transmis...
