Unmanned Aerial Vehicles (UAV) [PDF]
, 2014 It is envisioned by the FAA that by 2016 UAVs will be flying in the NAS in fairly large numbers. There will be an increased need for TE potential hazards cannot be easily mitigated by aircrew action. Human factors and workload must be evaluated with respect to the envisioned mission, which may require long missions at remote sites.

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band
Advanced Materials Technologies, EarlyView.An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...
