How to thermally cloak an object
Using sound waves to make patterns that never repeat
Collaboration between mathematicians and engineers could lead to customizable materials.
Thin to win
U engineers develop a thin, lightweight lens that could produce slimmer camera phones, longer-flying drones and thermal imaging cameras, such as for finding victims of natural disasters.
