Abstract :
We present in this paper an electromagnetic model based on finite elements method for the characterization of dielectric samples with a near field microwave microscopy, this proposed model is a useful tool to determine for, a given microcopy probe, the minimum substrate thickness required to extract accurately the substrate relative permittivity and loss tangent. This paper proposes a practical application with a wideband characterization apparatus.
