Shipboard electromagnetic interference is a major problem for FRP or wooden hull ship. Electromagetic disturbances to electronic and electric eqipment on board the ship are mainly caused by its own radio transmitters. Some experiment has been made to find out materials which are good for electromagnetic shielding and show high resistance to eddy current on the surface of materials at the ship's rolling movement.
It has been found that knitted wire mesh, punched metals and expanded metals-these matreials show high resistance to the eddy current in themselves-are not effective materials for shielding large space. This paper gives technical information about electromagnetic shielding, such as testing method of material and construction, and general notes for having good electmagnetic shielding for FRP or wooden ship.
