Low-Power Solar Sail Control using In-Plane Forces from Tunable Buckling of Kirigami Films
Gulzhan Aldan, Igor Bargatin
We present a proof-of-concept study showing that buckled aluminized polyimide films perforated with millimeter-scale cuts can redirect normally incident light obliquely and generat…
Kirigami Film Reflector for Deployable Space Antennas
Gulzhan Aldan, Henry Love, Matthew Campbell +2
We propose a low-pretension reflective kirigami film as a material for the reflective surfaces of large deployable space reflector antennas with an operating frequency around 10 GH…
Photophoretic Light-flyers with Germanium Coatings as Selective Absorbers
Zhipeng Lu, Gulzhan Aldan, Danielle Levin +2
The goal of ultrathin lightweight photophoretic flyers, or light-flyers for short, is to levitate continuously in Earth's upper atmosphere using only sunlight for propulsive power.…
Minimizing the Ground Effect for Photophoretically Levitating Disks
Zhipeng Lu, Miranda Stern, Jinqiao Li +6
Photophoretic levitation is a propulsion mechanism in which lightweight objects can be lifted and controlled through their interactions with light. Since photophoretic forces on ma…
Controlled photophoretic levitation of nanostructured thin films for near-space flight
Mohsen Azadi, George A. Popov, Zhipeng Lu +5
We report light-driven levitation of macroscopic polymer films whose bottom surface is engineered to maximize the thermal accommodation coefficient. Specifically, we levitated cent…
