An apparatus includes a containment vessel having an interior space configured to be sealed. The interior space is configured to receive at least one reservoir of liquid to be vaporized during a decontamination process. The apparatus also includes a base configured to be inserted into the interior space. The base is configured to receive one or more pieces of personal protection equipment to be heated and decontaminated within the interior space during the decontamination process. The base is configured to hold the one or more pieces of personal protection equipment above the at least one reservoir of liquid. The apparatus further includes a pressure-relief valve configured to be opened to release a pressure within the interior space. In some cases, the apparatus may include a filter configured to filter material passing through the pressure-relief valve.

Containment vessels for rapid thermo-chemical decontamination of facemasks or other personal protection equipment (PPE)

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.

Steerable antenna on platforms, fixed or mobile, are tracked to form an RF communication link by setting the width of the main lobe of the antenna beam pattern to be greater than the initial pointing uncertainty region and then concurrently scanning and progressively reducing the widths of the main lobes as the pointing uncertainty region is reduced to first acquire and then track the opposing antenna. The width of the main lobe is reduced such that the width of the main lobe is approximately fixed for each block. The antennas at opposite ends of the communication link may be scanned with scan patterns that are orthogonal to each other such that the demodulation of the received signal levels to signal direction of arrival at each platform is solely a function of the scan pattern of the receive antenna.

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.

A low-loss band and polarization-selectable gender-selectable transceiver for use with a reflector-type antenna suitable for the E-band frequency allocation as well as other RF bands in which the upper and lower bands are separated by a stop band. In addition to providing the gender-selectable combination of the upper and lower bands for transmit and receive, this topology allows for the selection of transmit, and receive polarizations. A transceiver may transmit and receive on the same or on orthogonal polarizations. Paired transceivers may transmit on the same or on orthogonal polarizations. This is accomplished by integrating a rotatable polarizer (e.g. a &#xbc; wave plate) and a polarization duplexer (e.g. an orthomode transducer) in a FDD (Frequency-Domain Duplexed) system. The rotatable polarizer allows for selection of both transmit and receive bands and polarizations.

A power amplifier uses a modular architecture in which each of the one or more modules spatially combines the power from multiple amplified channels. The individual modules are configured to operate in the EHF band and above at low loss. This entails reconfiguring the input and output splitters, the end-launched transitions between the amplifier chips and the input and output splitters and the packaging of the DC power and control board. The input splitter uses a split-block technology. The output splitter maps each amplified channel into a two-dimensional aperture.

A modular solid-state MMW power source based on a topology of the lens array amplifier provides both the flexibility to scale output power and effective thermal management. The modular power source includes a single submodule that uses one or more power dividers and one or more solid-state amplification stages to divide and amplify an RF input signal into R amplified RF signals. The submodule is mounted (suitably in the X-Y plane) on the surface of a heat sink, suitably coupled to a cold backplane, to remove heat. R 1:N low loss power dividers route the amplified RF signals to R*N radiating elements. Each of the 1:N power dividers suitably reside in the X-Z plane and are stacked in the Y direction to provide a planar output of the R*N radiating elements in the Y-Z plane. Placement of the amplifier chips on the single submodule decouples the number of amplifier chips, hence output power, from the number of radiating elements. Placement of the amplifier chips away from the radiating face provides a short path with large thermal cross-section through the heat sink to the backplane to remove heat. The topology can produce high output power combined with a high antenna gain to produce large power-aperture products previously only achievable with a Gyrotron. As amplifier chips become more powerful, the topology can be adapted to use fewer chips.

A foldable reflect array may include a plurality of geometrically-flat reflect antennas. Each of the reflect antennas may include a respective plurality of antenna elements to receive and retransmit an incident wavefront, and each of the plurality of reflect antennas may be foldably coupled to at least one other of the plurality of reflect antennas.
