Measuring lunar simulants in the terahertz band

Laboratory measurements of polarized terahertz emission show that apparent bulk permittivity can be estimated even for simulants with lunar-like surface roughness, supporting the interpretation of remote sensing.

How angular grains change vibration-driven flow

Laboratory experiments and simulations reveal different flow behaviour for angular and rounded particles under vibration. The results highlight the importance of particle shape when interpreting the movement of planetary regolith.
