Variable Emissivity Modeling for Sustainable Lunar Surface Habitats
S. Keller, S. Stewart, S. Taylor +1
Lunar habitats will be one of the first platforms to enable long-term human presence beyond Low Earth Orbit. These structures act as a stepping stone for exploring our solar system…
Steerable Radiation Forces with Frequency-Detuned Acoustic Metasurfaces
Sam Keller, Matthew Stein, Ognjen Ilic
We demonstrate that acoustic waves can induce controlled translation and rotation of macroscopic objects through small, but deliberate, detuning of the driving wave frequency. When…
Adaptive and ultrabroadband thermal control with solid-state nanophotonic emitters
Daniel Kindem, Sam Keller, Karl Pederson +3
Managing the emission and absorption of thermal radiation is crucial for a wide range of technologies, from radiative cooling of buildings and vehicles to thermal regulation of sat…
Multifunctional Lightweight Radiators for Small-Satellite Thermal Control
Karl Pederson, Sam Keller, Daniel Kindem +2
Thermal management in small satellites is constrained by limited radiative area and strict mass budgets, necessitating the development of radiator structures that are simultaneousl…
