Thin amounts of plastic wrap, wax paper, cotton and rubber are not likely to interfere with radio waves. However, aluminum foil, and other electrically conductive metals such as copper, can reflect and absorb the radio waves and consequently interfere with their transmission.

Copper is the most reliable material of choice when shielding from radio frequencies because of its ability to absorb both magnetic and radio waves. It is also highly effective in attenuating magnetic and electrical waves.

At lower frequencies in the MF, LF, and VLF bands, diffraction allows radio waves to bend over hills and other obstacles, and travel beyond the horizon, following the contour of the Earth.At medium wave and shortwave frequencies (MF and HF bands) radio waves can refract from the ionosphere.

Copper is the most preferred material for radio frequency shielding, as it is capable of absorbing both magnetic and radio waves. Radio frequency shielding is often provided for government and corporate buildings.
