Abstract
An investigation of the dielectric properties of powdered materials us ing a parallel plate waveguide is presented. The numerical model is im plemented using a finite element method with a TE10 mode current sourc e. Small particles are simulated by applying the dielectric constant t o a random selection of triangles in the material region. In the two d imensional case, an adaptive mesh technique is implemented to obtain a n efficient mesh. A comparison with analytic models and measurements i s provided.
