IWTh4: Disruptive Paths to RF Innovation with Additive Manufacturing & Thermal Cooling

Presentation Abstract
Recently, powder-bed fusion metal additive manufacturing (AM) process has matured as a breakthrough technology for the development of RF and microwave components such as waveguides, filters as well as antennas. Additive Manufacturing of RF Waveguide Components showed several advantages over the traditional/conventional machining process especially when it comes to part weight reduction and design flexibility. Critical discussions will also cover the challenges that remain. Surface roughness, material anisotropy, and process variability can degrade RF performance if not properly managed. Standards for material characterization, dimensional accuracy, and RF testing are still evolving.
