The shielding of radio waves by conductive coatings

A theory is given of the shielding of radio waves by the conducting coatings which are placed over the cockpit dome and windows of an airplane. At low and medium frequencies the shielding arises primarily from the quasi-electrostatic charges which are induced on the surfaces the effects of which increase strongly with decreasing frequency. At higher frequencies the shielding from this source diminishes in importance while that from the induced eddy currents increases in effectiveness.
