High-dielectric-constant composite material for additive manufacturing of GRIN apertures

Unmanned Areal Systems and electromagnetic spectrum control are increasingly important parts of naval warfare.  The combination of these two technologies can provide myriad capabilities, but the costs of modern phased array antennas are often too great to include on UAS.  GRIN apertures provide an attractive alternative, but suffer from poor manufacturability.  Lynntech will address this difficulty by producing a new high-dielectric-constant resin for SLA additive manufacturing.  The high dielectric constant of the proposed material allows for much thinner and lighter apertures to be created for a given performance, combining the performance of lamellar drilled PCB designs and the low cost of 3D-printed designs.
