Abstract: A radome structure may include an inner tuning layer component and a laminate component overlying the inner tuning layer component. The inner tuning layer component may include a thermoset foam or a thermoplastic foam. The laminate component may include a first fiber reinforced dielectric layer, a second fiber reinforced dielectric layer overlying the first fiber reinforced dielectric layer, and a third fiber reinforced dielectric layer overlying the second fiber reinforced dielectric layer. The first fiber reinforced dielectric layer may include a first low dielectric constant material. The second fiber reinforced dielectric layer may include a first high dielectric constant material. The third fiber reinforced dielectric layer may include a second low dielectric constant material.

Abstract: The present disclosure relates generally to a layered structure for a radome for use with radiation of a free space frequency. The present disclosure relates more particularly to a layer structure for a radome having a core with an inside surface and an exposed outside surface. The core includes a first core layer having a first relative permittivity of at least 2.3 and a second core layer having a second relative permittivity of at least 2.3. The first core layer is no more than 0.75 mm from the outside surface of the core. An inner structure is disposed on the inside surface of the core and has at least one layer. Each of the first relative permittivity and second relative permittivity is at least 0.4 greater (e.g., at least 0.7 greater, at least 1 greater, or at least 1.3 greater) than a relative permittivity of any layer in the inner structure.

Abstract: Embodiments of the present disclosure are directed to a composition and composite for protecting a transmission/reception device. The composite can include a reinforcing material and a cured epoxy composition impregnating the reinforcing material. The cured epoxy composition can contain reaction constituents including less than 50% stoichiometric amount of an anhydride curing agent to an epoxy resin. The composite can exhibit synergistic improvements in mechanical strength, weatherability, and signal transmission properties.

Abstract: An annular seal including a body defining a central lumen and a weakened portion disposed around the central lumen. In an embodiment, the weakened portion includes at least one aperture or a plurality of apertures. In a further embodiment, the apertures may be identical to one another. An annular seal including a body defining a central lumen bounded by a sidewall, wherein the body has a dual-elastic modulus profile including a first elastic modulus, S1, as measured along the sidewall prior to assembly with an inner component, and a second elastic modulus, S2, as measured along the sidewall after assembly with the inner component, and wherein the first elastic modulus is less than the second elastic modulus.

Abstract: A bio-reactive container and filter assembly to improve flow rates and mass transfer without increased pressure. An inlet filter membrane secured to the container defines a container chamber in combination with the container. An inlet filter membrane element may also be secured to the container to provide structural support to the membrane. An outlet membrane secured to the container defines a container chamber in combination with the container. An outlet filter membrane element may also be secured to the container to provide structural support to the outlet membrane. Inlet and/or outlet filters and/or filter elements are constructed to significantly increase surface area available for fluid and/or gas ingress and/or egress. Single and double layer membranes with mixtures of hydrophobic and hydrophilic characteristics are used to maximize perfusion and gasification/degasification of bio-reactive containers.
