Propagation Effects of Temperature Variations of Moon Regolith

Gray, D., Kontis, K. and Le Kernec, J. (2022) Propagation Effects of Temperature Variations of Moon Regolith. In: IEICE Technical Committee on Antennas and Propagation (AP), Tochigi, Japan, 19 Aug 2024, pp. 29-34.

Abstract

The Moon’s surface temperature ranges from -193°C to 107°C over which the regolith relative permittivity changes from εr=1.4+j0.5 to εr=2.7. The effects of this variation on propagation at 2.5GHz between a pair of dipoles and a pair of patches over the Moon’s surface were modelled by empirical equation and full wave simulation. The peak and null positions for each antenna configuration did not change with temperature-dependent εr . The only appreciable effect was a small decrease in the peak amplitude caused by εr″.
