All metal passive waveguide components are key building-blocks of several RF systems used for telecommunications, navigation, imaging, radio-astronomy, and cosmology. The accurate manufacture of these devices in Additive Manufacturing (AM) technologies can open the way to a high integration level of microwave functionalities with a significant cost and mass reduction. In the paper, after an introduction...
This work reports on the integration of RF functionalities in microwave waveguide components through the selective laser melting process. A specific integrated component has been developed for the relevant application domain of satellite communications. The component operates in the Ku-K bands and integrates a H-plane bend, a 90-deg twist and ninth-order pass-band filter. The AlSi10Mg prototype manufactured...
This paper presents the developments at CNR-IEIIT and IIT concerning microwave waveguide components manufactured through selective laser melting (SLM). The latter is an additive manufacturing process based on the selective melting of a metal powder bed through a laser. Application of this technology to the development of antenna-feed chains aimed at satellite communication (SatCom) is discussed. Description...
Agile and versatile legged robots are expected to become useful machines for applications in unstructured environments where traditional vehicles with wheels and tracks cannot go. Hydraulic actuation has proven to be a suitable actuation technology due to its high power density, robustness against impacts and high stiffness for high bandwidth control. In this paper we demonstrate how additive manufacturing...
