Abstract: An aerodynamic nose cone capable of imaging through the nose cone is accomplished by forming the nose cone as an Afocal Axicon lens. Under a condition of RI≈cos(X)/cos(3X) where RI is an effective refractive index and X is a cone half angle of the solid right-circular cone. EMR incident on a front portion of the cone undergoes a total internal reflection (TIR) and exits a trailing surface of the cone with approximately the same parallelism with which it entered the cone. EMR incident behind the front portion of the cone that exits the trailing surface with different parallelism than it entered may be directed to a light dump or through a frustum of a cone to re-establish the correct parallelism. The entire optical system may be monolithically integrated into the nose cone to eliminate alignment issues and moving parts.

Abstract: A system includes a containment vessel configured to receive and retain equipment to be decontaminated. The system also includes a solar reflector configured to reflect solar energy towards the containment vessel in order to heat the containment vessel. The system further includes end supports configured to receive and retain the solar reflector and the containment vessel. The system also includes a base having or coupled to multiple side supports, where each side support is configured to contact and support a corresponding one of the end supports. In addition, the system includes one or more semi-transparent solar shades configured to reduce the solar energy reaching the solar reflector and the containment vessel.

Abstract: A multi-axis self-contained sensor system includes an outer spherical housing and an inner spherical housing. The outer spherical housing has a transparent spherical shell that surrounds a first cavity and having a first refractive index (RI). The inner spherical housing is in the first cavity and is completely surrounded by the outer spherical housing. The inner spherical housing has a first average density and includes a spherical wall that surrounds a second cavity. A sensor system is contained in the second cavity, and a suspending fluid layer is interposed between the outer spherical housing and the inner spherical housing. The suspending fluid layer is composed of a fluid having a second RI.

Abstract: A monolithic, wideband, millimeter-wave radome is provided. The radome includes a solid layer formed of a single material and a lattice layer formed of the single material and disposed on an exterior surface of the solid layer. The lattice layer includes void regions formed from selective omission of the single material during lattice layer buildup.

Abstract: A waveguide-to-waveguide power combiner/divider including a waveguide including a first opening at a first end of a first section of the waveguide in a first plane and n openings of n sections at n other ends of the waveguide, wherein n is a positive integer. At least one of the n sections is bent in at least one plane different from the plane of first section, and the first section and n sections each have at least two sides that are broader than at least two other sides; and n−1 walls within waveguide configured to divide a height of first section into n heights. Each of n sections has a height equal to one of the n heights, wherein the n−1 walls are located at a junction of the first section and the n sections and extend toward the first opening of the first section.

Abstract: An apparatus for and a method of a coaxial-to-waveguide power combiner/divider. The apparatus includes a single-fin coaxial-to-waveguide power combiner/divider, including a waveguide having one open end, one closed end, and two sides that are broader than two other sides; two fins in a plane within the waveguide, wherein the plane is configured to be parallel to the broader sides of the waveguide; and at least one coaxial input joined to each of the two fins. Signals may be applied to the at least one coaxial input joined to each of the two fins are in phase with each other, and a number of the at least one coaxial input joined to each of the two fins may include one of a same number and a different number.

Abstract: An apparatus includes a capsule configured to be launched or carried towards an unmanned aerial vehicle (UAV). The apparatus also includes a directed energy device within or carried by the capsule. The directed energy device includes a first inductor configured to generate an inductive magnetic field that is able to inductively couple into one or more electronics of the UAV in order to disable or destabilize the UAV. The capsule can be configured to be launched towards the UAV and can include a loiter mechanism (such as a rotor, umbrella, or parachute) configured to maintain a position of the capsule or to slow a descent of the capsule after launch. The capsule can also be configured to be carried towards the UAV by a different UAV, and the apparatus can further include a tether coupling the capsule to the different UAV.

Abstract: A low-loss millimeter-wave radome is provided. The low-loss millimeter wave radome includes a perforated and plated metallic plate and a low-loss dielectric encapsulation material to encapsulate the perforated and plated metallic plate. The perforated and plated metallic plate includes multiple metallic sheets and electrically conductive plating. The multiple metallic sheets respectively define a periodic array of sub-wavelength holes and are laminated together such that the periodic array of sub-wavelength holes combines into a periodic array of perforations.
