Figure 17 shows JSC-1A Lunar regolith simulant used for 
measurement of complex dielectric constant.
The following table shows Values of dielectric constant of 
terrestrial analogues of Lunar soil for temperatures from -196° C 
to +200°C at 1.7GHz & having density 1.8 
gm/cm3.Measurements were made at ICRS.
The Graph below shows that dielectric constant of terrestrial 
analogues of lunar soil ε' & loss factor ε'‟ increases with 
increasing temperature from -196C to +200C at 1.7GHz
