Antenna Reflectors Based On Stretchable Perforated Thin Films
Kirigami-based metamaterials with tunable properties for large, lightweight, and cost-effective parabolic antennas for space applications. Problem: Parabolic antennas used in space currently have a maximum diameter of about 20m. Larger antennas (e.g., with diameters of up to 100 m) would be highly beneficial, but launching such large payloads presents...

Controlled Levitation of Nanostructured Thin Films for Sun-Powered Near-Space Flight
Levitation of polymer nanocomposite film upon illumination in upper atmospheric conditions. Problem: Airborne objects cannot sustain flight within the mesosphere, the upper layer of the Earth’s atmosphere. This layer, which resides 50-80km above the Earth’s surface, lacks the air density needed for airplane lift yet is too dense for satellite...

Ultrathin robust plate nanomaterials
Technology Overview: The nano-honeycomb shells have been fabricated from ceramic materials via atomic layer deposition. The thickness can vary between 20 and 70 nm, and the largest single sheet measured 0.5 cm x 1 cm in area, creating sheets of the material at sizes that are visible to the naked eye. Other comparable low-density materials are very...

Fracture-resistant and ultrathin nanocardboard for structrual applications
Hollow, sandwich-like nanostructure that is joined by periodic, rigid webbing to increase bending stiffness and prevent fracture. Technology Overview: Mechanical metamaterials are increasingly used for structural applications. In particular, sandwich structures consisting of two planar face sheets connected by a webbing or foam core, can provide...
