Statistical Electromagnetic Absorption and Shield Properties of Inhomogeneous Compound Layers with Lossy Particles and Fibers
Electromagnetic wave properties in plastic and ceramic compounds containing high resistance and high conductance parti­ cles are discussed for electromagnetic shield and absorption by stochastic field theory and experiments. In order to have non-reflection and absorption composite materials, foundamental characteristics of inhomogeneous electromagnetic shield and absorption compound layers are investigated. Quasi-static properties and high frequency properties are shown for optimum design of wide band and thin compound layers by quasi­ static potential consideration and random wave methods. Inhomogeneous lossy plastic compounds of thickness 10mm containing carbon and metal particles and fibers, which have reflection and transmission factors of -17d3 and -26dg are experimen­ tally shown.
