Brief Abstract:
This dissertation presents novel process parameterizations and electromagnetic and mechanical optimizations in the development of new and improved additively manufactured (AM) high frequency electronics. A multidisciplinary approach is applied toward several key areas which have been shown to be knowledge gaps in the present state-of-the-art to support continued advancement and adoption of these technologies including 1) 3D printed shielded interconnects for enhanced immunity to EMI; 2) printed interconnects for high-power applications; 3) impedance mismatch in printed interconnects to bare die MMIC's; and 4) surface roughness in aerosol-jet printed transmission lines and interconnects for RF/microwave electronics.
