Description
Summary:Abstract Additive manufacturing of co‐fired low temperature ceramics offers a unique route for the fabrication of novel 3D radiofrequency (RF) and microwave components, embedded electronics and sensors. This study demonstrates the fabrication, materials analysis, and RF characterization of a multi‐material bismuth molybdate—silver (Bi2Mo2O9—Ag) artificial dielectric fabricated by laser assisted direct ink writing. The proposed fabrication technique enables 3D printing of dissimilar materials while minimizing inter‐material diffusion through the liquid phases. The permittivity of the artificial dielectrics increased up to 99% over the investigated frequency range (8–12 GHz) compared to the fabricated pure ceramic sample.
