An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

3D Printing Additively manufactured microwave electronics have the potential to feature prominently in the ongoing communications revolution by delivering previously unattainable levels of circuit miniaturization, weigh reduction, and conformal and flexible circuitization. In article number 2402715, Christopher Areias and Alkim Akyurtlu present a novel analysis of process induced surface roughness in aerosol-jet printed transmission lines, where electromagnetic simulation and process optimization are combined to minimize loss and maximize the performance of printed microwave electronics.
