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…

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.…
