Faraday Cage and Dielectric Shielding, Travertine (Calcium)
On this video you see about a foot thick of travertine, calcium carbonate, which is similar to limestone, and dolomite rocks in water containers, which contain calcium and magnesium.
The main factor in energy assault weapons shielding from these types of radar is conductivity, a faraday cage, but dielectric material helps too. The faraday cage and its copper wire can also be seen.
