Abstract
This work presents the characterization of the effective conductivity of additive manufacturing materials used for the fabrication of high-frequency communication devices. Factors such as material type, porosity, roughness, and oxidation reduce this conductivity, leading to increased insertion loss in the manufactured devices. For characterization, an X-band cavity resonator on a rectangular waveguide was designed, and the quality factor was measured for different implementations using various techniques and materials. Conductivity values of up to 17.70 MS/m were obtained for metalized polymeric materials and up to 6.44 MS/m for metallic alloys.
期刊介绍：
Radio Science (RDS) publishes original scientific contributions on radio-frequency electromagnetic-propagation and its applications. Contributions covering measurement, modelling, prediction and forecasting techniques pertinent to fields and waves - including antennas, signals and systems, the terrestrial and space environment and radio propagation problems in radio astronomy - are welcome. Contributions may address propagation through, interaction with, and remote sensing of structures, geophysical media, plasmas, and materials, as well as the application of radio frequency electromagnetic techniques to remote sensing of the Earth and other bodies in the solar system.
