There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The research within this defense demonstrates the use of hybrid additive manufacturing towards millimeter wave designs. The research demonstrated novel structures below 10-GHz, from microfluidic structures to mathematically inspired fractal and Voronoi structures. After integrating novel improvements to additive manufacturing, new millimeter wave compatible systems are demonstrated, including the integration of novel 3D printed packaging for mm-wave AoP systems. Heterogenous fabrication for conductor and dielectric designs enables flexible SIWs, as well as demonstrate performance with the newly characterized materials (including additively manufactured BCB and PTFE) for next gen systems. Finally, novel gradient material structures that specifically are enabled with the use of additive manufacturing are demonstrated utilizing FDM and SLA processes for novel retroreflector topologies at mm-waves, ideal for tracking applications, including the demonstration of an omnidirectional Luneburg lens retroflector and a semi-flat Luneburg lens retroreflector for automotive radar uses, including markers for visually impaired self-driving vehicles.
