It has proven its ability to replicate conventional waveguides with a comparable electrical performance [1]. In this way, low-cost, lightweight waveguides with customized dimensions and shapes are realizable. Moreover, 3D printing enables the implementation of unconventional complex-shaped waveguide components, such as filters [2], [3], interconnects, or antennas [4], whose design is restricted by the engineer's creativity rather than by limitations of conventional fabrication techniques.en1527-3342202468087IEEETechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringJournal Article10.1109/MMM.2024.3378648Journal Article
