Abstract
An electromagnetic radiation absorbing material comprises doubly layered core particles dispersed in a dielectric binder material. The first layer dissipates radiation; the second layer is an insulating material which helps prevent the particles from conductively contacting each other, and prevents degradation of the first layer. The absorber may be applied to an electrically conductive material, and an impedance matching material may be used.
