Chemical Reduction of Intermodulation Interference Caused by Metal- Oxide-Metal Junctions Aboard Ship

Abstract

Intermodulation interference from metal oxide metal nonlinear junctions near high frequency transmitters and receivers is suppressed effectively by application of chemical mixtures that provide an alternate, low impedance current path across the junction. The chemical formulations incorporate conductive and high dielectric constant materials into polymers. The mixtures clean metal oxides from surfaces, inhibit further corrosion, and can be used as additives to MILSPEC paints and lubricants. The approach greatly reduces intermodulation interference from electromagnetically active junctions in shipboard applications. Specific Topics include Electromagnetic interference, Chemical suppression, Broadband noise, and Intermodulation interference.
