End-of-Life Considerations for Early Cislunar Constellation Design

As cislunar activity accelerates (Artemis, commercial relays, navigation beacons), the Earth–Moon system risks repeating the congestion and “design-now, mitigate-later” pattern seen in LEO. This project developed a quantitative, early-design framework that treats end-of-life (EOL) disposal feasibili...

Dynamic characterization of metamaterials based on selective emptyin

Dynamic characterization of metamaterials based on selective emptyin

This project investigated how additive manufacturing (3D printing) can enable locally resonant “metamaterial” structures for passive vibration suppression. I first established a non-destructive workflow to characterize material properties of printed PLA parts—especially Young’s modulus—using vibrati...
