Electromagnetic Shielding Degradation Of Composite And Metal Mil-c-38999 Connectors Due To Environmental Exposure

Abstract

Three types of MIL-C-38999 connectors were measured for shielding effectiveness both before and after exposure to a controlled simulated Navy fleet environment using a salt fog chamber. Two connectors types were made of compositematerial. The third type was a standard aluminumconnector. Shielding effectivenesswas measured over the frequency range of 1 to 10 GHz using m ode-stirred chamber techniques. This paper compares the degradation of shielding effectiveness of the three connector types resulting from the salt fog exposure.
