Abstract: An electromagnetic reflector composed of a non-knitted, non-metallic carbon-based material mesh, antenna system incorporating the reflector and method for fabrication are disclosed.

Abstract: Baffle and shutter assembly (BSA) includes a baffle defined by a tubular member having a proximal end, a distal end, and a lumen extending therethrough. A baffle cover disposed at the distal end extends across a major aperture defined by the lumen and includes a cover aperture. A shutter system disposed within the lumen includes a shutter panel having a shutter aperture, and a shutter door. A door distal surface faces the baffle cover when the door is closed and has a reflective coating. The baffle cover has a cover proximal surface which faces toward the shutter system and is highly absorptive of electromagnetic energy in the optical spectrum.

Abstract: Deployable reflector system includes a support structure and a reflector surface secured to the support structure. The support structure transition from a compact stowed configuration to a larger deployed configuration to deploy the reflector surface. The reflector surface is comprised of a carbon nanotube (CNT) sheet. The sheet is intricately folded in accordance with a predetermined folding pattern to define a compact folded state. This predetermined folding pattern is configured to permit automatic extension of the CNT sheet from a compact folded state to a fully unfolded state. The unfolding operation occurs when a tension force is applied to at least a portion of the peripheral edge of the CNT sheet. In some scenarios, the support structure can comprise a circumferential hoop.
