Abstract :
The finite element method (FEM) was used to calculate the transmission coefficient of frequency selective composites with regularly or randomly distributed conductive fibers for various volume concentrations of the fibers. The transmission coefficient was also measured with a free space measurement system. The computed results are consistent with measured data. It also demonstrated that FEM is an accurate tool to predict the microwave performance of frequency selective composites, as compared to the method of moments.
