    • Facing 5G New Radio (NR) Test Challenges
    • Communicating Via Long-Distance Lasers
    • The Purpose of Mixed-Effects Models in Test and Evaluation
      The simplest version of a mixed model-the random intercept model, where so-called random effects represent group-wide deviations from a grand mean-can account for day-to-day deviations in system performance while still allowing the results to be generalized beyond the few days of observed testing.
    • Review of Recent Capability Improvements in Ultrashort Pulse Laser Sources: Closing the Relevancy Gap for Directed Energy Applications
      A new generation of ultrashort pulse lasers (USPLs) have moved to new gain materials and new architectures that have realized not only an improvement in environmental tolerance, but also significant reductions in size, weight, and power consumption metrics.
    • Counter-Directed Energy Weapons: Defense of Air Assets
      The global proliferation of directed energy weapon technology presents a new threat for the United States as competitors try to capitalize on the technology's relative high potential of mission success and low operational costs.
    • Nonlinear Effects in Transformation Optics-Based Metamaterial Shields for Counter Directed Energy Weapon Defense
      Applying an iterative solution to the Maxwell equations may accommodate the nonlinear effects produced by directed energy weapons that are not accounted for by the transformation optics method currently used to design metamaterial structures.
    • MIL-DTL-32628/01-X Reusable EMI Shield Termination Band on MIL-DTL-38999 Electrical Connector Accessory Braid Termination/Tensile Qualification Test
      Reusable constant force spring force bands (CFSB), employed on shielded wire harness constructions to secure the shield onto the connector accessory/backshell banding platform in order to protect the wires in the bundle from electromagnetic interference (EMI), were evaluated for tensile strength performance as described in SAE AS85049? and AS85049/128?.
